## What is KnotNum?

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.

## Version history (last 4 releases)

### 1.3 — 2026-08-22

Balance and responsiveness.

• List mode no longer repeats itself at high levels: lists grow longer as you progress, and from level 70 stones appear on the board. Multiply and divide levels get a little more time — those chains take longer to spot.
• From level 140 the board gets denser: vortex tiles show up more often, and there can be two at once.
• The result screen and the transition between rounds no longer stutter.
• Small interface and feedback fixes.

### 1.2 — 2026-08-18

Two new mechanics for players who've gone deep.

FROM LEVEL 100
• Number tiles: a cell marked ±1, ±2 or ±3 counts as more or less than it shows. It opens up targets you couldn't reach otherwise — and makes you rethink familiar moves.
• The golden tile: it sleeps for a few moves, then wakes up. While it glows, your chain has to pass through it — and that chain scores double.

FIXES
• The joker no longer flashes its hidden value when a chain collapses — it shows the number it actually became.
• Plus a few small interface fixes.

### 1.1 — 2026-08-02

• Timer mode now mixes in movement rules. After a warm-up, short bursts of targets have to be chained without diagonals — or with diagonals only. A badge in the header shows which rule is active.
• List mode: levels with a movement rule now give you more time, so the restriction stays fair.

### 1.0 — 2026-07-25

No release notes.
