Tail Panic is a code-driven grid strategy battle. Chasers catch evaders; evaders survive until timeout.
Chase vs escape
Chasers capture adjacent evaders; evaders use grass vision, portals and skills to buy time.
Stars & skills
Step on a star +1, use a skill −1. Blink, speed, charge, stealth — resource management is the core strategy.
Deterministic maps
Each match has a fixed seed. Same seed → same layout for debugging, review and ranked play.
Four skills
Blink, speed, charge, stealth — each with its own use.
Blink
Dash up to 6 cells in your facing direction. Great for dodging obstacles, closing in, or creating distance.
Speed
For the next 3 moves, each forward step travels 2 cells. Chase harder or breathe while escaping.
Charge
Rush straight ahead until hitting an obstacle. You can still capture opponents mid-charge.
Stealth
Invisible for 5 steps — opponents cannot see you on the map.
