How to Play
Watch 40 coloured circles bounce around the screen. When you're ready, tap anywhere to place your explosion. It expands outward and any circle it touches will also explode, growing and triggering further circles in a chain.
- You get exactly one tap per game - make it count
- Your explosion expands, holds briefly, then shrinks away
- Each triggered circle creates its own expanding explosion
- The game ends when all chain reactions have finished
Tips and Strategy
Pro tip: Be patient. Watch the circles for 10-15 seconds before tapping. Look for moments when several circles converge into a tight cluster - that's your window.
- Tap in the centre of the densest group of circles for maximum initial triggers
- Circles near walls tend to bunch up - corners can be good spots
- Each explosion holds for a moment before shrinking, giving time for nearby circles to drift in
- Don't rush - there's no timer, so you can wait as long as you like
Scoring
Your score equals the total number of circles caught in your chain reaction, out of 40. Catching 80%+ is rated "Amazing", 60%+ is "Great", and 40%+ is "Good". Every circle counts the same - there are no multipliers.
