Signals arrive one at a time. Tap MATCH when the color you see now is the same as the one TWO signals ago. Not the last one — the one before it. It sounds trivial. It is not.
Colors arrive one by one. Press MATCH (SPACE, or tap the screen) when the current color equals the one two signals back. Miss a match or press on a non-match and it counts against you. Sixty seconds, or thirty signals in calm mode.
Three spots on this page — top, middle, foot — priced top-down. The machine runs on them. Nothing else here is for sale but vessels.
This machine is free and sponsor-fueled. Scores are for the board and for discounts on vessels — never for prizes behind a buy-in.
Every control is a big button, a number key, or a tap on the screen. Day mode is one tap. Every free machine has a DAILY board that is the same for everyone. Scores live on your device.
