Tentrix

Tentrix is a block placement puzzle game released in 2017 where every round hands you three shapes and challenges you to find room for all of them on the 10x10 grid. Place carefully — once a block lands, it stays. No undoing, no moving, no second chances on a bad placement.

Fill complete vertical or horizontal lines to clear them and keep the board open. The moment any block in your hand has no valid spot left on the grid, the game is over. If you enjoy puzzle games like Tetris Unblocked, Tentrix Game delivers a deceptively simple block puzzle that gets genuinely challenging fast.

How to Play Tentrix

  • Drag blocks onto the 10x10 grid using your mouse

  • Place all three shapes each round to receive the next set

  • Fill a complete horizontal or vertical line to clear it and free up space

  • Placements are permanent — think before you drop each shape

  • Watch for 3x3 block shapes — they appear frequently and take up significant grid space, so always keep a clear section of the board reserved for them

  • Game ends when any block in your hand cannot fit anywhere on the grid
