About
Play with numbers. Discover division.
Which number would you tap to start a chain reaction?
Sokyo is a number puzzle where tapping a red prime divides the numbers it can divide in the same row and column. When a result becomes prime, it triggers the next step in the chain. One thoughtful tap can set off a satisfying cascade.
DISCOVER THE CONNECTIONS
For example, 6 divided by 2 becomes 3. That new 3 can spark another division. Explore which numbers divide evenly and where the next connection might appear.
SEE WHERE TO START
Red tiles with a ring mark the primes you can tap. The how-to-play guide introduces the rules, so you can start by trying a move and watching the numbers change.
THINK ONE MOVE AHEAD
New numbers arrive every turn. Clear space now, or look for a bigger chain? Read the board and aim for a new high score.
PLAY TOGETHER OR SOLO
Ask “What happens if we tap here?” and explore the board together. Or enjoy a thoughtful number puzzle during a short break.
