Guide a growing trail across compact boards, choose a safe turn and see how far careful planning can take you. Every run is single-player and works offline.

Three ways to play
• Classic Survival starts on a clear 14 × 14 board. Collect targets, grow your trail and adapt as the pace rises. Additional barriers are previewed before they enter the board.
• Step Collection challenges you to gather six targets within 60 moves. Quick collections build a scoring streak.
• Route Chapters offer 40 compact courses with narrow passages, moving gates and one-way lanes. Progress is saved on your device.

Swipe in any direction or use the direction pad to steer. Direct reverse turns are ignored. Collect a target to grow by one segment, and avoid the board edge, your own trail and marked barriers. Pause whenever you need; movement freezes and a three-beat countdown begins before play resumes.

After a run, see your score, length, collection efficiency and the reason the trail ended. A one-use trail review lets you step through the last twelve positions before you restart from the beginning. A slow 8 × 8 practice board introduces turning, reverse input, growth and body collisions.

Adjust swipe sensitivity, movement pace, sound cues, vibration, motion, board markings and visual palette to suit your play. Scores, route progress and preferences remain on your device. No account or network connection is needed.
