Gold Mine Stacks 2 is an intriguing video slot game developed by Nailed It Games, offering players 20 distinct ways to win. The game is set on a traditional 5-reel, 3-row grid, making it familiar yet exciting for slot game enthusiasts. The theme of the game is centred around a gold mine, which is reflected in its symbol design and bonus features.
The symbols in "Gold Mine Stacks 2" are straightforward yet effective in conveying the game's theme. The lower-value symbols are represented by metallic J-A card ranks, which are common in many slot games. These symbols provide a payout of two times the player's stake for a line of five matching symbols. Moving up the paytable, the game features four high-value gem symbols. These gem symbols are more lucrative, offering payouts ranging from 8 to 20 times the bet for achieving a five-of-a-kind winning line. An important symbol in the game is the wild, which not only shares the same payout values as the top gem symbol but also appears on all five reels. Wilds in "Gold Mine Stacks 2" are multifunctional – they can create winning combinations on their own and also substitute for all other symbols, excluding the bonus symbol. This increases the chances of forming winning combinations and adds an extra layer of excitement to the gameplay.
The Gold Mine Stacks Bonus round is a standout feature of the game, activated by landing three or more bonus symbols in the base game. Upon activation, the triggering bonus symbols become sticky and remain in place for the duration of the bonus round. During this round, the reels will only display bonus symbols or blank spaces. The game features a progressive level system, displayed above the game grid, where bonus prizes increase as players advance through the levels, from Level 1 up to Level 16. At Level 1, bonus prizes range from 1 to 20 times the bet, and at Level 15, they escalate to between 15 and 300 times the bet. Achieving Level 16 grants players the maximum win. Players level up by covering a full reel with bonus symbols, which also clears the grid of bonus symbols for the next level. Before the bonus round commences, players encounter the Randomizer feature, which consists of two spinning reels.
