Spins Stone: a caveman, a mammoth and five eggs that decide your free spins

Five eggs sit in a row on the free-spins help page, each on a green card marked FREEGAME SELECT. Behind them are 5, 8, 10, 12 and 15 free spins, and you choose one. That pick is the main feature of Spin Stone (the logo actually says SPINS STONE), a cartoon Stone Age slot on SKY777.

The reels

It's 5 reels by 3 rows on 25 lines, set in a green prehistoric canyon with stalactites hanging at the top. The letters are carved out of cracked yellow stone. The pictures are a stone hammer with a red handle, a speckled egg in a nest, a woolly mammoth, a friendly green dinosaur and, at the top, a caveman with a club over his shoulder.

Five cavemen pay 4000 and five dinosaurs 2000. The mammoth pays 1000, the egg 800 and the hammer 600. A, K and Q pay 150 for five; 10, J and 9 pay 100.

The wild is a flat stone slab with WILD painted on it in red, and it only lands on reels 2, 3 and 4. It substitutes for everything except the scatter. In free spins it expands to fill the reel, and the help picture shows the dinosaur standing on the full-height version.

Campfire scatter and the egg pick

The scatter is a campfire in a ring of grey stones. Three or more anywhere start the Free Spins Feature, and you pick one of the five eggs. Free spins can be retriggered. The help pages don't mention a multiplier, and the scatter's own pay isn't listed on the pages I have.

A small win

At one line and 0.01, line 1 paid 0.20 and got the full BIG WIN treatment. The balance went from 24.38 to 24.41 across the captures.

Space Monkey is the other SKY777 slot where free spins bring extra wilds on the middle reels, and Shougen War uses the same bottom bar and FAST SPIN button. The SKY777 overview covers the app and accounts, and everything else is on SKY777 games. If you want to play, get a SKY777 game ID from a provider.
