A closer look

A little space to think.

Find your rhythm in a sky-filled Greek theatre. Drag equal neighbouring gems together to make bigger numbers, then line up a matching row to clear space.

New waves descend into a six-column board. Choose when to bring the next wave forward, keep room for the arrivals and build your personal best. A run ends when a new whole wave cannot fit.

How to play

  1. Choose a difficulty and start a game.
  2. Drag a gem into an equal neighbouring gem to merge them.
  3. Make a whole row of matching gems to clear it. Use Next wave to bring in a wave early, or tap falling gems to drop them.
  4. Keep space available for new waves and aim to beat your personal best.
