Three slot worlds wait around the old sunken lighthouse: a bubble tram, a glowing kelp maze and the lamp room hoard. Ride the tram straight away on a guest pass, and play everything with free coins.
A round glass tram humming along kelp cables between the shell-roofed houses, on twenty-five lines. It is the world you can ride on a guest pass, and its free round gathers speed stop by stop.
Two ticks and the tram doors slide open for two hours. Whatever you collect on the ride stays with you if you later make an account.
A free account takes a nickname, an email and a password, and starts with 100,000 coins. It opens the kelp maze and the lamp room, and nothing on the site is ever for sale.

Lanes of glowing kelp that twist towards a hidden clearing, on twenty-five lines. A starfish wild holds its place whenever a spin comes up empty.
