All four stones
Why four stones, and why all from one studio? Because a single workshop's hand shows in every piece it cuts. Play'n GO made each of these games, and setting them side by side lets you watch one studio treat the same material four different ways.
There's a square grid that clusters, a prism with a reel turned on its side, an emerald that grows extra facets as it plays, and a round stone that reads its lines from both ends.
Keeping to one provider also keeps the bench tidy. Every frame comes from the same demo server, behaves the same way after the age check, and shows demo credits as a plain number with no currency sign beside it.
Under the loupe, side by side
| Stone | Grid or reels | How symbols match | One feature |
|---|---|---|---|
| Gemix | 7×7 grid | Clusters of five or more, touching horizontally or vertically | A crystal meter that fires one of four effects |
| Prism of Gems | 5 vertical reels and 1 horizontal reel | Ways that change from spin to spin, up to 3,087 | Multipliers on the horizontal reel that rise to x7 |
| Perfect Gems | 6 reels, up to seven symbols each | Ways that grow as matched symbols split in two | Perfect Spins, a free spins round |
| Crystal Sun | 5 reels | 10 fixed lines, counted left to right and right to left | Expanding wilds that bring a re-spin |
Pick up a stone
Each card opens the stone's own page, where its demo slot loads in a frame after the age check. Whatever number the frame shows is a count of demo credits, worth nothing and never for sale.
Gemix
by Play'n GO
The plainest cut on the tray, and a sensible first stone. Matching jewels gather into clusters on a square board, and each cluster puts a little charge into a crystal meter.
- 7×7 grid
- Cascades
- Four crystal effects
Prism of Gems
by Play'n GO
Read it in two directions: the five upright reels cascade, while the reel lying across them gathers multipliers and holds the only wild.
- Up to 3,087 ways
- Wild on the sideways reel
- 10 to 20 free spins
Perfect Gems
by Play'n GO
Step-cut and patient. The middle reels open out, matched symbols divide, and a growing multiplier keeps pace with the cascades until the next spin.
- 6 reels with cascades
- Wild gem above the reels
- 9 to 27 Perfect Spins
Crystal Sun
by Play'n GO
The round stone of the four. Ten fixed lines count from either end, and every fresh wild keeps the re-spins turning a little longer.
- 10 lines, both ways
- Wilds on reels 2 to 4
- Re-spins
