The immersive and sleek presentation features a charming robot construction worker, and the futuristic theme adds to the overall experience.

Background and Theme

Build the bank characterThe cryptocurrency industry has been in a state of turmoil, with collapsing exchanges and an increasing number of rug pulls, which threatened the use of crypto for banking the unbanked. One possible solution for the future may be for people to construct their own banks instead of relying on digital assets to fill the void. Crazy Tooth Studio’s online slot, Build the Bank, explores this concept by allowing players to be accompanied by a robot with a construction focus in a game that includes a hold n’ win style round called Mega Pile.

The game is set in a city that is currently undergoing a building boom. Players are aided by robots, including the one that hovers beside the game grid, in their efforts to raise skyscrapers and construct a bank. The robot alerts players to scatter symbols and provides companionship throughout the game. The overall ambience is one of futurism and industry, with hints of Art Deco and EDM.

Build the Bank Mega Pile Bonus Features

For 3, 4, and 5-of-a-kind wins, the premium symbols pay out 0.12x your stake. However, if you land a full screen of the top-tier golden helmet symbol using the Any Adjacent Pays system, you can win a whopping 375x your stake. Scatter symbols can only be landed during the base game and can reveal a cash prize, special award symbols, a multiplier symbol, or a respin upgrade symbol.

Most of the scatter symbols only affect the Mega Pile feature, which is triggered by landing 3 scatters at the same time. In this bonus round, players are granted three rounds on an enlarged 5×7 grid. However, if the Mega Pile feature is initiated by a Respin Upgrade symbol, the rounds become limitless until the player achieves three consecutive rounds with only passive symbols (symbols that have no effect).

Mega Pile Feature

Each round of the Mega Pile feature offers cash prizes, multiplier symbols, special award symbols, and/or passive symbols.

build the bank mega pile featureWhen the Special Awards symbol appears, it generates cash prize symbols in every spot on the same row, column, or neighbouring location. Following each round, the multiplier and cash prize symbols drop to the lowest position available.

Multiplier symbols will boost all cash symbols on the same row, column, or adjacent symbols, and both symbols persist until the end of the feature. All the cash symbols are added together with the multiplier boosts at the end of the feature. The triggering scatter symbol determines the multiplier you get, and the feature cannot be retriggered.

In addition to the standard cash prizes, players have the opportunity to win Bank Prizes while playing the Mega Pile feature by filling the 3, 4, or 5 lower rows with cash and/or multiplier symbols. Each feature allows for only one Bank Prize win, and as the game progresses, the value of these prizes gradually increases. After being awarded, the Bank Prizes reset and start with initial values of 25x to 2,500x your bet.

It’s similar to Relax Gaming’s Dream Drop Jackpot feature and can yield up to 4,000x your bet. Build the Bank marks a new level for Crazy Tooth Studio, and it’s definitely worth a try.
