Core gameplay
Blocks have coloured symbols (circle, square, triangle). A row clears only when all cells show the same symbol. You can rotate the falling block to change its symbol orientation.

Level and content structure
Forty progression-based levels. Later levels introduce columns that lock for three seconds after a block lands.

Visual and user experience
Symbols are printed inside each block rather than relying on colour alone. The well uses a dark grey background. No screen transitions or cut scenes.

Features
A colour-to-symbol reference chart appears on the side of the screen. No online ranking or sharing options.

User value
Symbol-based matching assists users with colour vision differences. The locking column rule adds short-term memory practise.

Usage scenario
Evening puzzle sessions before other leisure reading.
