Features
Read full description

KnotNum is a number puzzle where you link neighbouring tiles into chains: add, subtract, multiply and divide your way to the target. No ads — none at all. No banners, no rewarded videos. Just you and the numbers. THREE MODES • Arcade — a campaign with endless progression: reach each level's goal chain by chain, earn stars for clearing levels, crack stones, and take on extra-tough challenge levels every 10th stage. • List — collect every number on the list before the clock runs out. • Timer — a race for the high score: every chain adds seconds, targets get harder with every tier. And your best goes straight to the Game Center leaderboard. DAILY PUZZLE A new puzzle every day, shared by all players, 10 stages long — the operation and target change with every move. Come back daily, solve the puzzle and collect your rewards. A BOARD THAT FIGHTS BACK Surprise tiles keep every round fresh: ×2 multipliers, a wild joker that can become any number, timer freezes, time bonuses and penalties. Watch out for the vortex — defuse it with a chain for a bonus, or it swallows the numbers around it. Some levels ban diagonal moves entirely, forcing you to think differently. FAIR BY DESIGN • The board is always solvable — no dead ends, ever. • On a losing streak? The game quietly grants bonus time or moves. • Hints, board shuffles and extra time — all of it can be bought with coins you earn just by playing. NO ADS, NO TRACKING We show no ads and collect no data. Progress lives on your device and the game works offline. Purchases are strictly optional: coin packs and a one-time Premium (coins ×2 forever). ALSO INSIDE • Achievements and stats — in-game and in Game Center • Daily login reward and a hint bank • Beautiful native design — full experience on both iPhone and iPad • Localised in English and Russian One chain and you're hooked. See for yourself.
