tu93 — ARC-AGI-3 game guide

Level 1

• Four moves only: up, down, left, right. There is no click and no undo.
• The board is White pads joined by short Gray wires on black. A move slides your token along a Gray wire to the next White pad. You can only go where a wire leads.
• Land on the solid Green square to clear the level. Each level has exactly one.
• Your token is a Blue square with a Darker Gray dot. The dot turns to point the way you last moved.
• Pressing a direction with no wire still uses one step, but nothing on the board moves -- enemies stay put too -- so you cannot use it to wait for an enemy to pass.
• The step bar is a Pink line along the very bottom edge of the screen. Every arrow press uses one step, and the used part turns White. It refills on each new level: 50, 50, 35, 20, 50, 60, 30, 50 and 50 steps for levels 1 to 9.
• When the bar is empty you lose. A move that spends your last step and lands you on the exit still wins.
• Moves are animated one after the other: your token slides to the next pad first, then the enemies slide. You always finish your move before any enemy moves.
• There are no lives. Getting killed or emptying the bar ends the attempt on the spot, and after that only RESET does anything.
• RESET puts the level back the way it started: full bar, every enemy back in place.

Level 2

• Red square with a Purple dot: an enemy. It never moves on its own and never turns. The Purple dot is its front and shows the way it faces.
• Step onto a Red enemy's pad from its side or from behind and you bite it: it is destroyed. You can never reach it head-on, because you would have to stop on the pad in front of it first.
• Finish a move on the pad right in front of a Red enemy's dot and it bites: the dot turns Yellow, it lunges onto your pad and you die. It makes no difference how you got there -- walking straight at it or crossing in front of it from the side both get you killed.
• Every enemy follows the same contact rule: step onto the pad an enemy is standing on and it dies; be standing on the pad an enemy moves onto and you die. Enemies do not block your moves.
• The enemies take their move before the game checks for the exit. Landing on the Green square does not save you if an enemy reaches your pad on that same move.
• Anything destroyed -- an enemy or your own token -- bursts into a ring of eight dots in its own color that grows once and disappears.

Boss, 2026-09-16: Level 2 introduces an enemy: a red figure with a purple dot in it. Came at it straight on, then went around it and came at it from the side. Straight on, it bites you and kills you. Going around and coming at it from the side, you bite it and destroy it. The page never mentioned this enemy at all, and it is a huge mechanic.

Level 3

Level 4

• Orange square with a Purple dot: a patroller. Every time you make a real move, it steps one pad along its wire the way its dot points, and turns around where its wire ends. It does not chase you, and its dot never turns Yellow.
• Step onto the pad an Orange patroller is standing on and it is destroyed, even if it is facing you, because you move before it does.
• If an Orange patroller steps onto your pad you die, from any direction, including from behind. Its dot always points at the pad it will step onto next, so do not end a move there.

Level 5

• Level 5 has a second piece that looks exactly like your token (Blue square, Darker Gray dot). It is not you -- it is an enemy that bites like a Red one. It sits in the bottom-right corner facing off the edge of the board, so nothing can ever stand in front of it and it cannot bite. Step onto it and it bursts.

Level 6

Level 7

• Dark Red square with a Purple dot: a sleeper. It stays still until you finish a move exactly two pads straight in front of its dot. Then its dot turns Yellow and it is awake. Standing one pad in front of it, or beside it, does not wake it.
• A sleeping Dark Red enemy dies if you step onto it. An awake one cannot be caught that way: it is always two of your moves behind you, never one pad away.
• Once awake, the Dark Red enemy moves every time you move. Its first two steps go straight ahead, to the pad where you woke it. After that it copies the move you made two turns earlier, so it walks your exact path two pads behind you. Double back on yourself and it walks into you.

Level 8

Level 9

• Level 9 uses all three enemy kinds, and its Green exit sits on the pad right in front of a Red enemy's dot. Walking straight onto the exit gets you bitten; that Red enemy has to go first.
