Gemix is Play'n GO's colourful 7x7 cluster-pays gem cruncher, where wins explode off the grid and fresh symbols cascade in to keep a single spin rolling. Each symbol cleared adds to the crystal meter, and the action moves through three fantasy worlds that each bring a feature of their own.
Game mechanics
Wins on the 7x7 grid come from clusters: 5 or more identical symbols touching horizontally or vertically. The winning symbols explode and new ones drop in from above, so one spin can chain several wins in a row.
Every symbol removed by a win charges the Crystal Charge meter, and clearing 20 or more in one spin triggers a random bonus modifier. Alongside this, the game moves between three themed worlds, each with its own pattern to complete and its own special feature.
Features
- Crystal Charge. Remove 20 or more symbols in a single spin to trigger one of four random modifiers: Nova Blast, Crystal Warp, Light Beam or Chain Lightning.
- Super Charge. Clear 40 or more symbols in one spin and the Crystal Charge win is boosted with a 3x multiplier.
- Nova Blast. One symbol explodes and destroys the symbols adjacent to it, opening space for a fresh cascade.
- Crystal Warp. Every instance of a randomly chosen symbol warps into another symbol, tightening the grid for bigger clusters.
- Light Beam. A symbol fires a beam across the grid, transforming the symbols it hits into matching ones.
- Chain Lightning. Lightning arcs between two corner symbols and transforms every symbol it strikes along the way.
- World Features. Each of the three worlds adds its own twist on losing spins, from miner's lamps to spreading lollipop wilds and sticky spellbook wilds.
Why Gemix has five RTP settings
Play'n GO's own game data for Gemix lists five RTP versions: 84.9%, 87.66%, 91.66%, 94.78% and 96.83%. Each version keeps the name and artwork, with the maths tuned to a different long-run return. The casino picks which one it runs, within any minimum its regulator sets. Studios say they offer several because markets differ: minimums vary between regulators, and casinos weigh taxes, margins and commercial terms. A higher setting does not guarantee a profit, and a short session can finish up or down either way. This demo uses virtual credits: nothing is deposited, withdrawn or paid out, so the setting has no financial effect.

How to play the free demo
- Count the gems in each group after a spin of the Gemix demo: a cluster on the 7x7 grid needs 5 or more matching ones touching horizontally or vertically.
- Watch the crystal meter as wins cascade: clearing 20 or more symbols in one spin fires a random Crystal Charge modifier, and 40 or more adds the 3x Super Charge.
- On losing spins, look for the current world's own twist, such as miner's lamps, spreading lollipop wilds or sticky spellbook wilds.
Why try the Gemix demo
Four different modifiers can follow a clear of 20 or more symbols, so a longer session is the way to see Nova Blast, Crystal Warp, Light Beam and Chain Lightning each reshape the grid. The miner's lamps, lollipop wilds and spellbook wilds each belong to one of the three worlds, which means they only appear once the game reaches that world.
