TenTrix borrows the line-clearing goal of Tetris but strips away much of the stress. It keeps the puzzle thinking and strategy of the classic, while the tension comes mainly from your own decisions rather than from speed.
Three pieces wait below the grid. Drag one onto the board and release it where it should sit; once all three are placed, a new set appears. Full rows and full columns both disappear and turn into points. Shapes include L pieces, small L pieces, straight lines and squares, and none of them can be rotated, so an awkward piece has to fit as it is. The game ends when nothing left in your set can be placed, which makes keeping a wide empty area open a smart habit. 1010 Deluxe works on a similar grid idea.
