One-tap arcade: time each rail connection, build streaks and charge Overdrive.
Tap when a rotating energy coupler aligns with the glowing rail, then build streaks and charge Overdrive in RailSpark. This one-touch timing arcade game has no advertising and requires no user account.
Eight complete preview runs are included. A permanent one-time purchase unlocks unlimited play. Twin Current is available as a separate optional expansion after unlocking the full version.
Every connection is based on skill. Build long streaks, improve your multiplier and chase increasingly precise locks as the speed rises.
TAKE THE RISK
The cyan rail is always the safe target. When a narrower gold rail appears, you can wait for it and earn double points. Later, Flux couplers visibly accelerate and demand sharper reactions.
CHARGE THE OVERDRIVE
Successful connections fill your Spark Charge meter. Perfect hits and gold rails charge it faster. Fill the meter to activate three Overdrive connections with double scoring.
