Every duel moves your Elo rating, just like chess. Climb the tiers from Rookie to Grandmaster and prove you're the sharpest calculator in the world. NEW: THE SHOP & KEYPADS Earn coins as you play and spend them in the shop: neon, mechanical, ink, retro-LCD keypads and more, unlocked level by level. Your keypad, your style. FRIENDS & FRIEND CHALLENGES - Add friends by username, follow their stats and rank. - Challenge a friend in one tap: the challenge lands right in their app, with problems calibrated halfway between your two levels.
