Burn out every one of your opponent's filaments. The first grid wiped off the board loses.
Tap or swipe toward one of the four pulsing sockets around your head (the bright dot). One move, then your opponent goes. The lit panel and the banner show whose move it is.
A new filament lights at 20%. Each time you extend your chain, the four behind the new one brighten a step — up the ladder 20 → 40 → 60 → 80 → 100%. Every hit removes 20%, so a full filament takes five hits to kill.
Step back onto one of your own filaments to relight it to 100%. It costs your move.
Step onto an enemy filament (red ring) to dim it and its touching filaments by 20%. You stay standing there — nobody crashes. At 0% a filament burns out and knocks its neighbors down another step, so weakened grids collapse in chain reactions.
First player to step on it banks a Strike. The green Strike button appears: arm it, then tap any enemy filament on the board. It and its touching enemy filaments are destroyed outright. Spends your move.
Step on it and your entire grid instantly brightens one step (+20%).
Grow to 10+ filaments and your newest one gets a red glow: an entire enemy attack costs it only 20%, then the shield pops. Laying your next filament re-forms it.
The Surge button buys a second move in the same turn. Three per game, shown as dots.
Each card shows your filament count (flashes red at 3 or fewer), total glow, filaments lost, and tags for a banked strike or an active shield. The round counter sits bottom right.
Wipe every enemy filament and you win instantly. If the game reaches round 70, the player with the most filaments standing takes it.
