Diamond Rush

Diamond Rush is a Red Tiger Gaming slot set deep in a mine, where sacks of gold and glittering diamonds line the walls behind five reels, three rows and 20 paylines. A miner is the wild, and he lands stacked to cover more of the reels.

The free spins round changes the shape of the game. Three scatters on reels 1, 3 and 5 award 10 free spins in which the reels can grow to twice their size, adding 10 paylines with each expansion, while premium symbols and wilds land stacked. Random features also strike in the base game: Little Dragon Big Wins pays instant wins of up to 50x the total stake, and Happy Dwarf Bombs blast the reels. Medium volatility, a 94.53% RTP, stakes from €0.20 to €200 and a €240,000 top win make it a lively, feature-rich pick.

The mine provides a rich backdrop, with bags of gold and sparkling diamonds around the reels, which sit in the centre of the screen. The control panel beneath them holds every button a player needs, and the soundtrack suits the treasure-hunting mood.

Despite the detailed graphics, the game loads quickly in a web browser and needs no download. Volatility is medium, and the colourful presentation and steady rhythm make it a good recommendation for newcomers and experienced players alike.

Wins need at least three matching symbols in a row on one of the 20 base-game paylines.

• Premium symbols: a pickaxe, molten gold, diamonds and rubies pay from 35 coins for three up to 600 coins for five.
• Lower symbols: the card ranks A, K, Q, J and 10 pay from 10 coins for three up to 120 coins for five.
• Wild: the miner is the most valuable symbol, paying 90 coins for three and up to 1,000 coins for five.

Stakes run from €0.20 to €200 per spin.

• Stacked wild: the miner substitutes for all symbols and can land stacked.
• Free spins: three scatters on reels 1, 3 and 5 award 10 free spins.
• Expanding reels: during free spins the reels can expand up to twice their size, adding 10 paylines with each expansion. Premium symbols and wilds appear stacked throughout the round.
• Little Dragon Big Wins: a random feature that awards instant wins of up to 50x the total stake.
• Happy Dwarf Bombs: a random feature in which dwarf bombs explode across the reels to create wins.

Players set a stake from €0.20 to €200 and spin the 20 base-game lines. The miner wild lands stacked, so a single reel of wilds can join several line wins at once. At any point the random features can step in: the little dragon may award an instant win of up to 50x the total stake, or the happy dwarf bombs may blast the reels for new wins.

Three scatters on reels 1, 3 and 5 start the free spins. As the reels expand to as much as twice their size, each expansion adds another 10 paylines, and with premium symbols and wilds arriving stacked, the bigger grid gives the round most of the game's top-end potential.

The top win of €240,000 is 1,200 times the €200 maximum stake. Random features in the base game keep players engaged between free spins, and expanding reels are easy to show in a promotional clip. The wide stake range lets one title serve casual and high-stake players.
