How to play
- Move and rotate the falling piece so it fits the board: ◀ ▶ to move and ⟳ to rotate.
- Drop it into place. A complete row disappears and scores points.
- In Classic and Two Zones, a row made of a single colour is a Prism and scores a big bonus.
- The game ends when the pieces reach the top. Try to beat your best score.

Three ways to play
Relaxed
Every piece is the same colour and falls slowly. Just fit the pieces and clear lines.
Classic
Two colours. Clear rows of one colour to make Prisms. After five pieces you can invert a piece’s colours once per piece.
Two Zones
The board is split into two halves. You choose where each piece lands, and each half clears its own rows.
The Comet
From time to time a special Comet piece arrives. Its core changes the colour of the blocks around it, which can complete a single-colour row.
Statistics and daily streak
See your best score, games, lines, Prisms, Comets and time played for each mode, plus your streak of consecutive days.
