Hot Gems opens ‘somewhere deep underground’ with an animated sequence, starring a hillbilly miner who strikes a tsunami of coloured gems. He surfs the wave of jewels-a-plenty, bursts his way through the top, and the game begins. It sets the tone perfectly for what’s to come.

The game’s leading character is a bearded hillbilly, the music is banjo-pickin’ good, and the graphics are simple and cartoon-like. Pause too long between spins and our hero appears to do a little dance.

The online slot has five reels and 25 win lines. What makes Hot Gems such a cool game is its collapsing reels feature. When you hit a win, the symbols involved explode to leave empty spaces. These are then immediately filled by new ones and potential winning combinations. In theory, you can win indefinitely.

Symbols in play are a variety of multi-coloured gems, the hillbilly miner, an oil lamp, miner’s pick and cart. The wild is the word ‘wild’ and appears only on reels 2, 3, and 4. The miner is the game’s jackpot at 5,000x the line bet.

Line up the Free Games logo anywhere on reels 1, 3, and 5 and you start the free games feature with collapsing reels multiplier. You get 15 free games and every time you start a collapse, the multiplier for that win increases up to a maximum of 5x.

The Hot Gems online slot is a blast to play and - at Mansion Casino UK. Like any reputable internet casino, we encourage our customers to experience the online slot before playing for real money.

If you like the game, there is a real money Welcome Bonus worth up to £200 waiting for you when you make your first deposit.
