What happens in the game

Coloured blocks carry numbers. You select a block with the cursor, drag it across the grid and place it. When two identical blocks meet they join, and completing a line clears it.

The challenge is room: if you let the board fill up, play ends. Clearing lines is how you keep space free.

Suited to

Players who like number and block puzzles and prefer planning to reflexes.

Useful to know

  • Keep a free corner for awkward blocks.
  • Look for pairs before you place a block, not after.
  • Clear lines regularly instead of saving them for later.
  • Avoid scattering blocks across the board; grouped blocks leave more open space.
