Nock: Arrow Cube Puzzle

A cube stands in the dark, covered in arrows. Tap one and it slides away along its own path — but only if nothing is in its way. Every arrow you clear opens the road for another, and there is always an order that works. Finding it is the game. THE RULE An arrow leaves by following its own body out, so only the way in front of its head has to be clear. Arrows bend around corners, and they run over the cube's edges onto the next face. The six faces are one surface, not six separate puzzles. THE CAMPAIGN 500 levels. The first cube carries three arrows on a 4×4 face. The last carries 340 on a 16×16, with 83% of them locked when the board opens. In between, the difficulty climbs through five bands — Easy, Gentle, Medium, Hard, Brutal — and the level list shows you the whole ramp at a glance. Every level is solvable. Not "probably": each cube is built backwards from a winning line, so a solution provably exists, and clearing an arrow only ever frees others. You can never trap yourself. You can only be wrong about the order. LIVES Five lives, and they belong to you, not to the level. Tapping a blocked arrow costs one. Running out does not throw your board away — the cube stays exactly as you left it and the taps simply stop. A life comes back every 30 minutes, counted off the clock, so it keeps arriving while the app is closed. Or watch a short ad and take one now.
