TenTrix

About TenTrix

TenTrix is a block-placement puzzle played on a 10x10 grid, built around Tetris-style polyomino shapes that never fall and never rotate. You're given three shapes at a time and must drag each one onto the board; completing a full row or column clears it and makes room for more. There's no timer or gravity pushing pieces down, so the challenge is purely spatial planning: fit all three shapes before choosing where to place the next batch, and keep the board from filling up.

How to play TenTrix

1. Look at the three shapes shown below the 10x10 grid.
2. Click or tap a shape and drag it onto the grid to place it.
3. Fill an entire row or column with blocks to clear that line and score points.
4. Place all three current shapes; once they're used, a new set of three appears.
5. Keep planning ahead so a piece always has room to fit - the game ends when no piece can be placed.

Controls

• Desktop: Mouse only: click and drag a shape from the tray onto the grid, then release to drop it.
• Mobile / tablet: Touchscreen: tap and drag a shape onto the grid with your finger, then lift to place it.

TenTrix tips & strategy

• Don't rush to fill the center - build outward from a corner or edge so you always have open space to maneuver.
• Try to keep at least one row and one column open at all times; a fully boxed-in board ends the game.
• Since pieces can't rotate, think about all three current shapes together and place the most restrictive one first.
• Clearing multiple lines at once (a row and column together) scores more, so look for setups that complete two lines with one placement.
• Avoid creating small isolated gaps (like single-cell holes) that no upcoming shape can fill.

What makes TenTrix fun

TenTrix strips away the falling-block pressure of classic Tetris and replaces it with untimed, drag-and-place strategy on a 10x10 grid, so every game rewards careful planning over quick reflexes. Its clean structure of picking three unrotatable shapes at a time makes it easy to learn but hard to master.
