Survive 25 seconds.

Cells ignite, heat, then burn out. Tap them before they do — hotter cells are worth more, and one burnout ends the run.

A quick taste of the game. The app adds a campaign, daily challenges and arcade modes.

How it plays

Read the colour. Beat the burnout.

Tap a lit cell before it burns out. The hotter it gets, the less time you have.

  1. Idle

    Dark cells can wait.

  2. Fresh

    A cell lights up. Tap to clear it.

  3. Warning

    Amber means time is running out.

  4. Critical

    Red means act now.

  5. Burnout

    Too late. The level decides the cost.

The campaign

New levels. New pressure.

Learn the rhythm, then take on new patterns, tighter goals and boss milestones. Earn stars to open the next tier.

  • Goals and deadlines

    Hit a score, survive the clock, or finish without a miss.

  • Patterns that move

    Read lines, diagonals, Shape Shifter formations and the Ember Snake.

  • Mixed pressure

    Random cells and patterns arrive together as the difficulty builds.

  • Stars and bosses

    Aim beyond a clear with star targets and boss milestones.
