Squiggle

How to play

Tap the left half of the screen to turn left, the right half to turn right — your squiggle keeps moving on its own. Steer it onto green and yellow pills to grow longer and rack up length; red pills shrink you back down (or end the round outright on Hard). Reach the target length before you run into a wall, an obstacle, or your own tail.

Scoring & strategy

Target length climbs with difficulty — 10 on Easy, 15 on Medium, 20 on Hard. Easy wraps around every edge, so there's no wall to fear. Medium adds lethal top and bottom walls while the sides still wrap, and eating pills speeds you up. Hard walls off all four sides (with a couple of gaps to slip through), spawns obstacles over time, and speeds up automatically the longer you survive.

Watch the length counter in the corner — it tracks your progress against the round's target. Your best length per difficulty is saved and shown on the ready screen, so beating your own record is the real long game.

Rewards

Reach the round's target length and you're granted a Brain Burst on the spot — you don't even need to stop playing to collect it. Keep growing past the target for a new personal best.
