$1.99 · Designed for iPad. Not verified for macOS.

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. - Increasing challenge as you play - Save your current game and resume later - Light and Dark appearances - English and Japanese - No ads or in-app purchases Tap.
