The Spark — you. Slide in a straight line until something stops you. You leave a forked lightning trail showing the line you came in on.

Energy Core. Collect every one to power the exit. Grab them back-to-back for score-boosting combos.

Exit Node. Stays dark and inert until all cores are collected — then drift into it to clear the level.

Wall. Solid. Stops your slide dead. The edge of the grid does too.

Stop-Pad. Halts your slide right here so you can change direction mid-room. This is your steering — most puzzles hinge on it.

Surge Spike. Touch it and you're fried — instant reset of the level. Never slide across one.

Wormhole. Slide into one and you teleport to its twin — keeping your momentum, shooting out the far side. They come in matching pairs. Each wormhole fires at most once per slide (then it's just floor for the rest of that slide), so you never get trapped looping between them.

Switch. Slide over it and every gate in the room flips open↔closed. Hit it again to flip them back.

Gate. A wall when closed, open when a switch flips it. Plan which side of the switch you need to be on.

Key. Pick one up by sliding over it. It lets you punch through one lock.

Lock. Blocks you like a wall until you're carrying a key — then you pass and it opens.

Brittle Wall. Slam into it and it shatters, opening a new path. One-time.

Diode. A one-way gate — you can only pass it the way the arrow points (◀ ▶ ▲ ▼). From any other side it's a wall.

Virus. Hunts you. Every move you make, it steps one cell toward you. If it touches you, you die. Keep your distance and lead it into corners.

Move. Arrow keys or WASD. On a phone, swipe the board or use the on-screen d-pad.

Hint — H. Flashes the optimal next move (solver-powered). Works on any level.

Undo — Z. Rewind a single slide instead of restarting the whole room.

Restart — R. Reset the level. Enter / Space = next level on the clear screen.

Esc = back to menu · M = mute. Tune palette, motion, skins & keys in ⚙ Settings.

Stars. Clear at or under par moves for ★★★ — a perfect line. Slower still clears it. 1000 levels × 3 = stars to chase.

Campaign — a love story. You're an electron (e⁻) racing across the Grid to reach your proton (p⁺) and become a true atom. Levels 1–52 tell it in cutscenes; 53–1000 are the endless Deep Grid.

Duel. P1 = Arrows (green), P2 = WASD (cyan). Same grid, shared cores — first spark to escape wins.

Endless Run. Escalating grids, 3 ⚡ charges, one life-or-death run. Climb deep for score.

Time Attack & Daily. Race 10 nodes against the clock, or take on one date-seeded grid a day to build a streak 🔥.

Level Editor. Build your own grids, verify they're solvable, and share them as codes.
