Coin Lamp is a slot game by Booongo set against an Arabian-themed backdrop with purple skies and a magic-lamp motif. The reel layout can expand during play as symbols are collected, adding three extra rows and increasing the number of active positions on the grid.
The bonus game is triggered by landing four matching symbols on the middle row. It features respins, Coin Bonus Symbols with different values, Collect symbols that gather visible values, and Mystery symbols that can reveal a Bonus, Collect or Jackpot symbol. A Mystery Jackpot Symbol may also transform into Mini, Minor or Major jackpot prizes, while random multipliers up to x10 can land during respins and combine on the same cell.
Coin Lamp also includes Super Bonus Game and Power Bonus Game features, each with a guaranteed multiplier at the start. The Power Game begins with all three extra rows already unlocked, and filling all 24 positions on the expanded grid can award the Grand Jackpot. A demo version is available to play for free and practice before playing for real money.
