A crew appears on the deck for a moment, then vanishes. Which of the three decks below is the one you saw? Every level adds a body and shortens the look. Pure spatial memory.
Watch the deck — the crew shows for a moment, then hides. Pick the deck you saw from the three below (tap, or 1 · 2 · 3). Two of them are wrong by exactly one body.
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.
