Frequently Asked Questions

How do I play?

Swipe in any direction to slide all tiles. When adjacent tiles sum to 0 under the current modulus, they pop and vanish. Clear enough tiles and the modulus shifts — new rules, new complements, new strategy.

What is modular arithmetic?

Think of a clock: 5 hours past 7 o'clock is 12, which wraps back to 0. That's mod 12. In Modulo, tiles pop when their sum equals 0 under the active modulus. For example, 5 + 7 = 12 ≡ 0 (mod 12).

What's the difference between the game modes?

• Endless: The core experience. The modulus shifts as you play, spawn pressure increases, and a timer keeps you on your toes. Chase your high score.
• Zen: No timer, no pressure. Pick your modulus and experiment freely. Great for learning.
• Challenges: 15 hand-crafted puzzles with specific goals. Clear the board, reach a target score, or clear a set number of tiles.
• Daily Challenge: A new puzzle every day, same for everyone. Compare your results.

The game seems too hard / I keep getting game over

A few tips:

• Focus on creating complement pairs before swiping — plan one move ahead.
• Large pops (3+ tiles) give you bonus time and reset spawn pressure.
• In Zen mode, practice with smaller moduli (mod 5 or mod 7) to build intuition.

How do I restore my purchase?
