Cubra is an arcade game that combines elements of the classic snake game with the mechanics of 2048. Your snake consists of cubes with numbers that are powers of two. As the head moves across the field and eats blocks, identical cubes merge and their values double, creating a chain reaction that travels down the tail.
On the arena, there are 40 snakes at once: you and 39 opponents with different behaviors — aggressive hunters, peaceful feeders, and cautious players. You can collide head-on with a weaker snake, causing it to break apart into blocks that you can collect. Or you can sneak up from the side and bite off a piece of someone's tail.
Every block you eat and every victory earns points for the shared bank. Between rounds, you can use these points to upgrade your starting head size, speed, and block magnet. The further you progress, the higher the numbers get — there's no limit.
A round continues until your snake is eliminated. Can you become the largest snake on the arena and climb to the top of the leaderboard?
How to play
Control the snake with a single finger or mouse – the snake's head moves where the cursor goes.
— Eat blocks with numbers no larger than your head's number. If the block is too big, it will just be pushed aside.
— When you eat a cube, it becomes part of your tail's beginning. If neighboring cubes have the same number, they merge and double. When a cube reaches your head, its number doubles too.
— In collisions, the bigger head wins, while the loser breaks into blocks.
— You can bite off a piece of an opponent's tail: segments no larger than your head will become yours, and the rest will scatter across the field.
— After losing, you can resume the round once by watching an ad.
— Between rounds, visit the shop: use points earned in all runs to buy enhancements like a higher starting head number, speed, and a magnet.
