Snake
A nucleotide serpent in six pixel-art gardens. Plan your route, leave space for your tail, and chase mastery medals—or try Classic and Motif Hunt.
Original pixel arcade · six-stage campaign
Campaign · Standard
Start when you are ready.
Arrows / WASD steer · swipe or use the directional pad · P pauses · Enter starts or resumes. Turns are buffered, one per movement tick.
Campaign map & game modes
Collect eight bases. The walls are solid.
Stages unlock in order. Practice can rehearse any stage. Earn palettes after 2, 4, and 6 clears—never permanent power upgrades.
Sound, controls & accessibility
Slower simulation and wider aim assistance use separate records. Visual preferences and control remapping do not. Reduced motion follows your device settings. Pause before remapping; Escape cancels a remap.
How to play & the biology behind the theme
Keep a return route. Each base grows your body by one cell. Avoid the walls, terrain, and your own body. Moving into the cell your tail vacates on that tick is legal. Marked edge arrows mean the arena wraps.
Two turns, no reversals. You can buffer two perpendicular turns; only one is applied each movement tick. Direct reversals, duplicate held keys, and extra inputs beyond the two-turn queue are ignored.
Campaign medals. Reach the base goal, beat the stage’s par time, and collect the optional gold bonus chip. The chip does not grow the snake. Every stage has a different arena and resets your length.
Motif Hunt. Three pickups include the next target base. Collect the displayed sequence from left to right. A wrong pickup still grows the snake but resets sequence progress; completing a motif earns 20 bonus points and introduces a longer target.
Practice. Rehearse any campaign garden and lower the simulation speed. Practice never changes your campaign unlocks or personal records. Standard and Expert have separate records.
Biology versus arcade. A, C, G, and T are the DNA alphabet. This ribbon is a collection history—not a synthesized RNA transcript. Motif Hunt is a string-matching puzzle, not a physical model of DNA polymerization or a claim that a particular short sequence has a biological function.
