PlayCascade The Chain Reaction Strategy Game
One marble. One whole chain reaction.
Place marbles, make cells overflow and take over the board with a single cascade. Play a friend on one iPhone or challenge the AI in four levels.
Quick answer
What is PlayCascade?
PlayCascade is an abstract strategy game for iPhone. Two players take turns placing marbles on a grid. When a cell is full, it overflows, captures its neighbours and can set off an entire chain reaction. Whoever owns every occupied cell at the end wins. Play two-player on one device or against an AI in four levels – fully offline, no account, no ads.
Why PlayCascade
Easy to learn, hard to master
can flip everything
A single marble can start a cascade that turns the whole game around. No lead is ever safe.
AI levels
Easy, Medium, Hard and Expert – from your first game to a real challenge.
Ads, subscriptions, tracking
No ads, no account, no data collection. Just you, the board and the next move.
How it works
The rules in three steps
Place a marble
Put a marble on an empty cell or on a cell you already own.
Overflow
When a cell holds as many marbles as it has neighbours – corner 2, edge 3, centre 4 – it spreads them out. Every neighbour turns your colour.
Take the board
One overflow triggers the next. Own every occupied cell and you win.
App preview
One game, many looks
Every theme changes the background, the board and the marbles. New themes are added over time.

How does PlayCascade work?
Players take turns placing marbles on empty cells or cells they already own. When a cell holds as many marbles as it has neighbours – corner 2, edge 3, centre 4 – it overflows: each neighbour gets one marble and switches to your colour. That can trigger further overflows. You win when every occupied cell is yours. Learn more →
