Kengo

The first player to create a stack of 5 different colored pieces wins.

In a column, only the piece (or stack) closest to the player is playable.
Each turn consists of stacking this piece (or stack) on top of any other piece (or stack) of the player's choice, provided the resulting stack does not contain two pieces of the same color.
It is only possible to play on an empty space if the piece is from a stack.
Finally, a piece (or stack) that the opponent has just played cannot be moved, but players can continue stacking on top of it.

The game can be played solo against Android or with two players.
The rules and gameplay are available in French and English.
The game has 5 difficulty levels.
The volume of the music and sound effects can be adjusted independently.

To keep things interesting, there are 5 different starting boards.
The game is offline and ad-free.
