Join a grumpy miner and his trusty donkey deep underground in search of glittering gems and gold in Miner Donkey Trouble. This grid slot uses a 7x7 layout with a Cluster Pays mechanic, where winning clusters explode to allow new symbols to tumble down for consecutive wins. Various special features like Donkey Destruction, Pickaxe Wilds, and Mega Symbols are triggered by collecting symbols, adding dynamicity to the cascades. Landing three scatter symbols initiates the Free Spins round, where all collected features carry over and offer colossal win opportunities.
