Tetri Mania Slot Review

The Tetri Mania game can be found at casinos offering Wazdan software. Wazdan is one of the better established software developers in the online gaming market having been in operation since 2010. Unlike many of the smaller casino software providers Wazdan offer a selection of casino table games featuring some of the major table games, with a strong focus on slots games. Wazdan do publish the RTP/House Edge information for their slots games within their games. As such we can say that the House Edge for Tetri Mania is 3.57%.

Tetri Mania is a 4 reel game that is 3 symbols high. The game uses standard paylines, with 9 in total playing from left to right.

Special Symbols

Wild – The Wild symbol is the “Joker”, substituting for all symbols other than Mystery and Scatter symbols. Wild symbols will double the bet when part of a winning payline.

Scatter – The “Gold Coin” is the game’s Scatter symbol, which will payout regardless of payline and is also the symbol needed to trigger the Free Spins feature.

Mystery – The “Question Mark” is the game’s mystery symbol. The mystery symbol acts as a Scatter, meaning it will payout regardless of paylines. Mystery symbols will payout between 10 and 200 times the bet in combinations of 3 and 4.

Bonus Features

Free Spins – You trigger the game’s Free Spins by landing 3 or 4 of the “Joker” symbols anywhere on the reels. You will be awarded 15 or 30 Free Spins respectively.

Cascading Symbols – Every time you land a winning combination the symbols that made up the win will disappear with existing symbols falling down and new symbols filling the gaps left, giving you another chance to win on a single spin.

Symbol Walls – Forming walls of symbols over 3 or 4 reels will multiply the bet by 2.


Tetri Mania is a simple looking game that is offering as much as I have seen from a Wazdan slots game before. With this game you get free spins, wilds, mystery symbols, cascading wins and even additional multipliers. The game might not look that great but there is plenty going on to keep you engaged as you play. The house edge is sitting just at the level that we would want to see, meaning Tetri Mania is offering decent value for money.
