Gem Trio

Gem Trio is a retro-styled slot from Pragmatic Play played on a very compact grid. Glowing gems and classic symbols pay along a small set of lines. Different types of wild symbols can land, including coloured wilds and a multiplier wild, and they stand in for everything except the gem scatters.

Instead of a normal scatter trigger, the bonus is built around collecting gems. Emerald, diamond and ruby gems are gathered as they land, and the right combination starts a bonus with its own modifier. The emerald version adds extra spins, the diamond version brings in prize symbols, and the ruby version adds an extra grid so that more symbols can pay at once.

It may suit players who like short, compact slots with a retro feel and a collecting goal. The free demo uses play credits only, and every spin is random, with no way to predict when the gems will line up.
