Review of Castle Builder II's Key Features
Get ready to go on an adventure on a large map

The best part about the Castle Builder II online slot is that it has so much content beyond the spinning reels. The theme is amazingly detailed and so players are entertained for long sessions. When the game starts, the player must select one of the two available characters. A third one will be unlocked after completing the game cycle with one of the others. Each character has special skills that can be useful when looking to build castles.

Yes, this is the main playing mechanics on which the game is based, building castles. Although it can sound a bit complicated, the process is fairly easy and we will explain it in the Castle Builder II slot review.

On the left side of the screen, there is a piece of land where the castle will be built. Different materials can be collected by getting winning combinations on the reels with the respective symbols. These will be added to the 3x2 grid in the lower left corner. Once a grid is full, it will be used to build one segment of the castle. The progress is displayed on top.

When the progress bar is completely filled, the castle is done and it is time to move on to the next project. The landscape also changes so there is always an incentive to keep on betting and exploring. The game map has different locations that can be unlocked along the way for bigger and better castles.

Rabcat has certainly built a superb online slot machine

The visuals easily put the Castle Builder II slot in a league of its own. Even if we just consider the part of the screen with the reels and the symbols, everything is nicely detailed and the animations are very cute. Then there is an entire other half that presents the different landscapes and castles found on the map. Everything is very immersive and so the slot machine looks more like a strategy video game than a betting option available at online casinos. Combinations can be formed on up to 15 lines, from left to right.

Get an extra prize after completing a castle

Winnings are not just collection on the reels. As stated in the Castle Builder II online slot review, the goal is to build castles. Multiple admirers can be attracted during the construction process. Once a castle is completed, it is time for the royal wedding and the player can help the princess or prince choose a suitable match.

The problem is that the admirers only present their wealth after the choice has been made. There are only pictures provided and these can be deceiving. The richer the selected partner, the bigger the reward will be for the player. As the game advances and the castles get larger, more suitors will be provided. This is why the best Castle Builder II tips would be to play long sessions and set a bet size that can allow that.

It is still possible to get help from the free spins mode

Although it is easy to forget sometimes that Castle Builder II is a video slot, it does have some familiar features to help players increase their winnings. Free spins are triggered by scatter symbols as three, four, or five scatters anywhere on reels award 10, 15, or 20 rounds for free.

The good news is that players not only earn payouts for free but they also continue to collect building materials during the bonus spins. Wild symbols can expand to cover an entire reel and thus help get more wins on the active paylines.

Continue building from your mobile device

The game is entirely available as a mobile slots machine. It is even possible to play for real cash and claim the big Castle Builder II jackpot of 5,000 times the stake for five wild symbols on a line. The payouts for completing castles will also be significant, especially when playing the advanced levels.

In fact, since the rewards get better as you play more, the Castle Builder II mobile slot is a perfect choice. Just log in and continue building at any point during the day. You can do this from an iOS, Android, or Windows smartphone or tablet without downloading anything. It loads quickly in the browser app and looks just as impressive on a touchscreen as it does on a monitor.
