Are Online Slots New to You? Just Follow the Steps Below:

  • The number of activated lines is the first setting.

In terms of Castle Builder II, it offers 15 paylines. You can select their number – 1 being the low and 15 the high. A piece of advice: If you desire this Microgaming slot’s payouts to be more frequent, just leave this setting on the max.

In Castle Builder II you can expect the 15 paylines to give out the payouts left to right. These prizes will come often. What’s unique about this 5-reeler is that it has less than 20 paylines. But that doesn’t mean much.

  • Now, the next step is toward your preferred credit size.

The coin size is adaptable in Castle Builder II game. Simply use the adjustment button. The 5-reel slot offers plentiful betting options, from £0.01 to £2 betting amounts.

The difference between this video slot’s coin and payline amounts is that Castle Builder II should be played on all 15 paylines if you are to win its jackpot. On the other hand, Microgaming made sure Castle Builder II offers flexibility regarding coin size, which means 5000x line bet – the biggest prize in Castle Builder II – is yours to win no matter what coin size you pick.

  • The line bet size is what will determine the winner size.

Whether you like it or not, Castle Builder II won’t let you pick this value; it’s always set at 1 coins per payline.

As mentioned above, Castle Builder II lets you pick from 1 to 15 using a specially assigned button.

You can dispose with Castle Builder II’s bet size option at your discretion. Seeking a fast way to wager as much as you can? No problem – there’s the ‘bet max’ button.

Apart from the easiness of use, this Castle Builder II option lets you place a wide range of bets – from £0.01 to £2 per every active payline. Considering that this (reel)-reeler provides such a range, it obviously targets mid- to high-rollers.

  • Ready, set, go! Just click on Spin and who knows – maybe £37500 will fall right into your hands!

Once you press this button, you’ll see the 5 reels start on the bet size you previously picked. Microgaming also included an auto play button with which Castle Builder II will make up to 100 spins in one round.

  • What’s the next step? Full screen and volume options, of course.

Don’t bother trying to play on full screen – Microgaming didn’t program that option.

You can use the mute button to turn off this video slot’s sounds and play in peace.

In terms of sound volume variations, Microgaming made this title somwehat old-fashioned – in this otherwise advanced title the on/off button is the only volume setting.

Symbols Explained

The imagery of this Microgaming title involves 10 symbols. The ones to really anticipate include:

  • The Builder’s Crown
  • The Builder’s Chest
  • The Gold Bar
  • The Builder’s Ring
  • The Iron Ore
  • On the other hand, the lowest Castle Builder II prizes can be won on the Wood.

But that’s not all. The 5 reels also carry some bonus tiles:

  • The Wild Horde – the stacked icon
  • the Castle Builder II wild symbol
  • The Free Spins scatter
  • The Free Spins which will award free spins

The biggest paying tile in Castle Builder II is Builder’s Crown. If you see Builder’s Crown 5x on any of the 15 paylines, it will reward you with 5000x your bet. If your bet level is £2 on all 15 lines, 5 Builder’s Crown symbols will get you 5000x your bet, or £37500.

Here you go, the top paying symbol:

Somewhat lower wins can be hit with the Builder’s Chest, which pays 1000x bet per line when 5 of them hit Castle Builder II’s reels on the minimum bet level, and £2000 when you decide to play on the max bet. The Gold Bar is the third strongest symbol in this Microgaming slot, for 5 of them multiply your line bet by 500 when you place 15 coins per line, and £1000 when you wager 15 per each active payline.

Take the Builder’s Ring and the Iron Ore symbols’ top prizes of 250x and 100x line bet and you’ll realize this Microgaming slot has more in store for you. Although modest, the Wood symbol’s prizes of the maximum 20-fold line bet are a decent bankroll booster when nothing else comes your way.

The good news is that this intricately designed slot has a wild tile that replaces any regular symbol needed for a win. This tile also has a 5000x line bet multiplier. And this is not the only special symbol Microgaming included.

Keep your eyes on the reels for the Wild, but remember that this video slot contains a scatter symbol too. So, these Castle Builder II’s special tiles make a superb match. Also, x total bet can be yours if Free Spins symbols appear anywhere on those 5 reels.

The fact that this ComeOn slot release features a Free Spins symbol that triggers free spins makes Castle Builder II’s offering even more attractive.

About the Castle Builder II Jackpot

There are no online slot jackpots here. Instad of a Castle Builder II jackpot, Microgaming decided to provide this game with a Builder’s Crown figure that will bring in a considerable amount by augmenting the Castle Builder II line stake by 5000x. If we say you bet the maximum £30 per spin you could win £37500. In other words, this regularly paying slot offers prizes that can’t be won in many other ComeOn games.

Microgaming’s Castle Builder II Progressive Jackpot

Sure, it’s good to have a progressive jackpot in a Microgaming slot, but when there isn’t one, there are other ways of boosting your ComeOn account. For example, the payline wager multiplier of 5000x and other profitable prizes could do well at replacing the progressive jackpot.

What’s the Difference Between Video and Classic Slots?

Players who enjoy video slots should try Castle Builder II. There is an exciting range of animations. Relying on its expertise in video slots, Microgaming made this game highly likeable. Its 5 reels contain some great features, while its 15 lines display animations for every win.

Did Microgaming Make Castle Builder II a 3D Game?

Castle Builder II is not a 3D slots game. The game is good, but Microgaming decided not to utilise 3D technology and graphics. Its 5 reels are fun to play anyway, with this classic slots game play at ComeOn casino being sure to keep you entertained.

Control Panel

Let’s now focus on this 5-reeler’s toggles:

Hit the Spin Button

With the Spin toggle you will start this 15 paylines slot. And once you do that, you’re setting yourself up for a 5000x line bet multiplier, frequently given prizes and heaps of fun, especially if you’re a Video Game theme fan. Furthermore, Microgaming inluded the following set of buttons:

  • Commands for controlling the sound
  • The Info button whick makes all the information and rules of Castle Builder II accessible with a click
  • The Max Bet option which will set the bet to the highest value
  • The Line Number switch which determines how much lines you’ll be betting on
  • The Bet Value command which lets you set the stake size

The Turbo Button

Engaging the Turbo setting will boost the speed of slot’s reels, along with its free spins making them go faster than normal.

Sometimes Fantasy-style slots, like Castle Builder II include a Turbo toggle which aims to give the 5 reels more speed. In fact, the rotating will have more speed in both the standard as well as the free spins rounds.

For reasons unknown, Microgaming did not include the Turbo setting in this 5-reeler even though it appears in many video slots.

Info Tab

Without the Information icon, Castle Builder II rules are not that easy to find. The best you can do is to ask the ComeOn staff.

Autoplay Button

Let’s say you have an itch to play Castle Builder II with real money you may wonder if this ComeOn game has the Autoplay setting, which plays the 5-reeler all by itself. Yes, it does, as Microgaming had the forethought to include Autospin in the slick Fantasy-style release, with up to a maximum of 100 spins, although it stops when it hits a prize.

No more clicking forever on the Spin toggle! This clever setting, called Autoplay, makes it easy for you to play with no stopping! Microgaming has also made this option customized to players’ needs. The number of automatic repetitions ranges from 10 to 100.

The Lowest Bet Amount

This video game gives you the prerogative to decide how low your Castle Builder II bet will be. Mind you, the lower you go, the less you’ll earn. But you shloud also take into consideration that this 5-reeler has some exciting special features which could make a difference when it comes to your balance.

Sadly, Castle Builder II was denied a Bet One button that would help you set the minimum betting value in one click. Admittedly, this can be a bit of a hassle if you want to get to playing this Video Game -styled slot as soon as possible, but it will just take you some more clicks to set the cash the minimum to £0.01.

The minimal Castle Builder II coin value is only £0.01. This means that instead of wagering £30 in a single spin, you can choose other amounts than the £2 maximum coin value. Lock the bet at 1 X 0.01 and it won’t exceed £0.01 total per line.

For this title, Microgaming provided an option to choose less lines than 15 paylines. What you should know, though, is that by doing so you would also lessen your chance to freespins which would be a great way to boost your winnings.

The Max Bet

This video game has a bet max option. Microgaming incorporated it so you can go all the way to the top with one push of a button. So if you are a highroller, this is a perfect thing for you. The simple math is: put the maximum value of a coin at £2 and the maximum coin bet per line at 1. Multiply that by all 15 lines and you get a bet of 15. Then all you are left to do is to spin the 5 reels and simply watch closely as those 10 money making symbols do their dance!

RTP Percentages Explained

This 5-reeler’s rate of payount, which is recorded during a certain period of playing, is called the RTP, or Return to Player. It is a well known fact that Microgaming titles commonly have an RTP which can span from 93% to 96%. This simply means that for every £100 you spend, the average yield you will be reeling in will be £96, and not that you’ll be winning in 96% of the spins.

There is an industry standard when it comes to RTPs and the Castle Builder II RTP falls into that standard: 95.5%.

Bonus Symbols

Playing this regularly paying slot is a joy thanks to its the Free Spins and the Wild symbols that boost its payout rate.


This 15-liner’s generosity relies on scatter, aka the Free Spins symbol, which Microgaming made as a pay-any symbol that awards x your win. The fact that Castle Builder II’s scatter also activates free spins means ComeOn players will get better payouts.

This is what it looks like:

Here’s What Happens When You Get a Wild

At those moments when you get 4 Gold Bar images and need just one more to line up 5 of them so you can earn 500x your line stake, this is when this Microgaming slot is really great: the wild symbol may come up and fill in for the much needed Gold Bar symbol.

Above is the pic of the Castle Builder II wild symbol.

About Castle Builder II’s Expanding Wild

Does Castle Builder II Have a Stacked Wild?

A nice aspect of this Video Game slot is the opportunity to hit some big wins with the help of its stacked symbol – the Wild Horde. What it brings you is the x line bet multiplier.

Castle Builder II Symbols that Spread over All 5 Reels

This video slot pays real money when you have 3 matching symbols. Your biggest win will be if you manage to pull off 5 matching images, one per reel.

In Castle Builder II, the regular symbol that pays the most is the Builder’s Crown. You can see from the paytable that the Builder’s Crown will pay you as much as 5000x line bet, providing you get all 5. Also, keep an eye on the Builder’s Chest symbol as it can make your line stake go up 1000 times. This Video Game-themed game also has the Gold Bar symbol that triggers 500 times your line stake if 5 of them line up. Your line wager can also be boosted 250 times by the Builder’s Ring symbol. Similarly, the 5 Iron Ore symbol activate the 100 times line stake multiplier. But, should all else fail, there is still the humble Wood that multiplies the wager 20 times. So look at it this way: playing this Video Game styled game will very likely do good by you, if only you keep at it.

For instance, achieving 5 of the Wood on a line of Castle Builder II will see you win £0.2 for the minimum bet amount of £0.01. Further to this, you can get £5 if you get 5 Gold Bar all lined up together. And if you feel really lucky, maybe wish for the maximum 5 Builder’s Crown symbols to come up, so you can win the maximum £50.

However, it’s not like you cannot do anything to make your playtime more enjoyable and, perhaps, lucrative.First of all, you can stop searching for online slot strategies, as there are millions of sites offering them, but very few with any actual advice you could use. Instead, use your common sense and set a budget first. Castle Builder II can be played with as little as £0.01 per line, so selecting all 15 paylines should not be a problem. In return, you get better winning odds.

The volatility in Castle Builder II is not difficult to describe. Payouts are rather frequent, but never too lavish. Another important aspect is RTP, which may reach 95.5% in this Microgaming slot. For sure, ComeOn finds this game profitable as well. However, this 5-reeler also brings nice amounts to players’ accounts.

Which goes a long way towards underlining our central point – playing Castle Builder II and other slots should be seen as something you do for fun, not something you do to try and win money. The RTP % that you’re likely to lose – ie the amount the slot machine retains from however much you put in – should thus be seen as your ‘pay to play’ amount, which goes towards providing you with the fun you get while enjoying the games.
