How to Play Speed Coin (prototype)
Quick start
- Try a small tilt on the opening platform.
- Keep the coin controlled as it rolls downward.
- Prepare the next platform before the coin reaches it.
- Finish through the bottom hole before chasing a faster bonus run.
Controls
Tilt the coin’s platform to control its roll. Guide it through the lower hole intact; the finishing time changes the bonus multiplier.
Speed Coin (prototype) — About this game
Speed Coin (prototype) rolls a fragile coin down a sequence of tilting platforms toward the hole at the bottom. Changing the platform’s angle guides the roll, but reaching the exit is useful only if the coin survives. The finishing time also determines a bonus multiplier, making speed a scoring choice that competes with careful handling. Learn a small tilt that keeps the coin under control before attempting a faster descent, then correct the next platform early rather than waiting until the coin has already rolled beyond its edge.
