Unlimited Treasures Slot by Evoplay

The grid starts at just three reels, but every winning combination pushes a new reel onto the right side. There is no cap on how many reels appear - as long as matching symbols keep landing on each new column, another one spawns. A History Board on the left side of the playing field tracks how many of each winning symbol have accumulated, and the final payout multiplies that count by the symbol's coefficient and the bet.

Wilds only show up from the 4th reel onward, never on the initial three columns. Each Wild adds +1 to every winning symbol's count on the History Board, which makes them far more valuable than a simple substitute. A x2 win multiplier appears above additional reels in the base game, doubling all accumulated symbol counts when it activates - but only if that reel actually extends a winning combination. During free spins, that multiplier upgrades to x2 or x3.

Four or more Bonus symbols anywhere on the reels trigger 10 free spins, with +2 for each extra Bonus beyond four. Retriggering works on a lower threshold: just three Bonus symbols during free spins award three more rounds, plus one per additional Bonus. The Bonus symbols also interact with the expanding reels - three on the first three columns add an extra reel, and a single Bonus on any subsequent reel does the same.

Win calculation here differs from standard payline math. Instead of paying per line, the game counts total matching symbols across all reels and multiplies that total by a per-symbol coefficient. The highest-paying symbol returns 3x per symbol counted, so landing it across six or seven reels with a Wild boost and a x2 multiplier stacks into serious numbers. The Arabian bazaar setting with its lamps, gemstones, and treasure chests fits the theme of limitless expansion.
