Cosmic Gems slot review
Cosmic Gems is a space-themed gem slot from 2by2 Gaming, played on 5 reels and 3 rows with 243 ways to win.

Three or more scatters trigger free spins, and Trophy Tiers change the game’s look as streaks build.

How Cosmic Gems plays
The reels float against a starry backdrop, and the symbols are polished gemstones. Cards from 10 to Ace are the low pays, coloured gems sit above them, and the diamond is the top-paying symbol. With 243 ways there are no paylines to pick: matching symbols on adjacent reels form the wins.
- Wild: appears on reels 2, 3 and 4 and substitutes for the regular symbols.
- Scatter: pays anywhere on the reels, up to 10x your stake for five, and three or more trigger the free spins.
The Win Streak and Trophy Tiers
A winning combination sets off the Win Streak. The grid grows from 5x3 to 5x4, the ways rise from 243 to 1,024, and you get a respin. Each respin that lands another win awards one more, so a streak lasts for as long as the wins continue and ends on the first respin that doesn’t pay.
Trophy Tiers run alongside the streaks. As you move up through them, the game upgrades its badge, logo, background and reel frame. They change the presentation rather than the prizes, so they work as a progress marker, not an extra feature.
The free spins sit apart from the streaks. Three scatters award 8 free spins, and four or five scatters award more. The larger 5x4 grid isn’t saved for a bonus round, though: it can appear after any winning base game spin.
