About game
Staring at the same document for hours leaves your brain feeling like mush and your motivation hitting rock bottom. Cubra arrives right on time to rescue your productivity by combining the addictive growth of a classic snake with the clever math of 2048. You navigate a chaotic arena filled with hungry rivals, consuming numbered blocks to grow your tail and increase your head value. Merging identical cubes creates powerful chain reactions that send your size skyrocketing instantly. Every segment added to your snake body makes you stronger, allowing you to smash smaller opponents and steal their hard-earned resources. Success requires constant movement because thirty-nine other snakes compete for the same limited pool of geometry. Upgrading speed and magnets between sessions ensures your future rounds start with a distinct competitive edge. Playing this browser-based io challenge takes zero setup since you can jump straight into the action for free right now.
How to play
Steer with one finger or the mouse: the snake's head follows the cursor.
— Eat blocks with a number no bigger than your head. A bigger block can't be eaten — it just gets pushed away.
— An eaten cube joins the start of your tail. Equal neighbouring cubes merge and double; when a cube catches up with your head, the head doubles too.
— In a head-to-head clash the bigger head wins. The loser shatters into blocks.
— You can bite a rival's tail: a segment no bigger than your head becomes yours, and the rest of their tail spills onto the field.
— After you lose, you can continue the round once by watching an ad.
— Between rounds, visit the shop: starting head number, speed and the magnet are bought with points earned across all runs.
