PrimeGrid is a minimalist number-sliding puzzle built on a 5x5 board with one empty space. Each level gives you a different reconstruction rule, from classic 1–24 ordering to prime paths and odd-even partitions. Slide tiles into the empty space to reshape the grid and satisfy the current rule. Earn stars based on your moves and time, and unlock achievements for mastery and efficiency. Simple visuals, deep logic—perfect for quick sessions or long-thinking streaks.
