Play Portal Snake online
Portal Snake is a wormhole-twisted take on the classic snake arcade game: guide Wriggle the grub across a 22x22 grid, eat apples, and grow — without hitting walls or yourself.
Two color-matched portal pairs let you teleport across the board. Enter the cyan gate and pop out of its cyan partner; same for the orange pair. Direction is preserved through the jump.
Every teleport triggers a 5-second x2 scoring window: food eaten while the bonus is active counts double. Chain teleports into feeding runs for the biggest scores.
Golden apples spawn every 15 seconds and vanish after 10 — each is worth 5 points (10 under the portal bonus). Eat 40 foods of any kind to win.
Portals relocate every 8 foods, and speed rises with every bite. Your best score is saved in your browser.

Tips for a better run
Teleport right before a golden apple to double its value.
Plan your exit before you enter: the portal keeps your direction, so line up the approach.
Portals relocate every 8 foods — glance at the new positions before the late-game squeeze.
Keep your tail loops wide; the board gets tight after 25 foods.
Eat during the 5-second bonus window only if the path is safe — a greedy bite into your tail ends the run.

Frequently asked questions
How do I play?
Steer with arrow keys or WASD, or swipe on touch screens. On the menu or game-over screen, press Space or tap to start/restart.
What do the portals do?
Two color-matched portal pairs sit on the grid. Drive the snake's head into one portal and it pops out of its partner instantly, keeping the same travel direction. It is the fastest way to cross the board — and to dodge your own tail.
What is the portal bonus?
For 5 seconds after every teleport, each food is worth double points: normal apples count 2, golden apples count 10. The bonus timer shows in the HUD.
Is Portal Snake a copy of another game?
No. Portal Snake is fully original: the wormhole-portal mechanic, the character Wriggle, the grid layouts, and all code, art, and audio are original works. The classic snake genre is inspiration only.
How do I win fast?
Use the portals to cut corners — a teleport plus the x2 bonus window is the fastest way to rack up score. Keep portals away from your escape route in the late game: they relocate every 8 foods, and a blocked exit cell is fatal.
