Store description excerpt
Tap a red number. Pop! It splits, chains, and the board clears away — and honestly, it's kind of addictive. Sokyo is a chain puzzle where you tap primes to clear the board. Play a few rounds and you'll get friendly with numbers without even trying. "What divides this?" "2×3 makes 6" — you pick up multiplication and division without it ever feeling like homework. Even if numbers aren't your thing, you'll just be playing a game. ■ Easy to learn Tap a red tile (a prime) and every number it divides in its row and column splits at once. If a split makes a new prime, that one fires too — a chain! The deeper you chain, the more clears at once and the bigger your score. New numbers keep coming every turn. Think a step ahead and see how long you can last before the board fills up. A perfect little brain workout for a spare minute. ■ Great for - A quick mental break - Anyone who loves numbers or puzzles - Getting comfortable with numbers through play (kids too) ■ Features - Simple rules, surprising depth - Gets tougher as you go - Light & Dark - No ads, no in-app purchases, no data collected - Don't know primes? You'll pick them up as you play Tap, chain, and clear them all.
