Dragon's Treasure Quest Slot by PG Soft

Each reel starts with three oversized symbol positions, and the expanding window mechanic splits them apart during cascades. When a big window participates in a winning combination, it cracks into two smaller windows on the next drop. One reel splits from 3 rows to 4, another to 5, and if all five reels fully split you're playing a 5x6 grid with 7,776 ways instead of the starting 243. The smaller windows stay locked for the rest of that spin's cascade chain but reset to three big windows on the next paid spin. It's a tumble game where the grid physically grows with each consecutive win.

Multiplier symbols are the other half of the base game math. Any regular symbol - the red-haired warrior, the purple-robed witch, the dwarf archer with his crossbow, even the card suits carved into dark stone tablets - can carry a multiplier tag between x2 and x100. These don't multiply individually. At the end of a full cascade sequence, every multiplier that appeared on any winning symbol gets added together and applied once to your total win. Land three symbols with x2, x5, and x20 across different cascades, and the combined x27 hits everything. A Feature Buy option skips the scatter wait entirely if you want to jump straight into the bonus.

Free spins award 15 rounds for four scatters, with a Treasure Chest Collection feature that can randomly add extra scatters mid-spin to guarantee the trigger. Inside the bonus, the same expanding windows and multiplier symbols apply, but now there's a persistent accumulator bar sitting below the reels. Every multiplier value from every winning symbol across every free spin gets deposited into that bar and never resets. By spin 10 or 12, you might be sitting on an accumulated x40 or x50 - and each new winning cascade still generates its own symbol multipliers on top. So the final payout on a late free spin gets hit twice: once by whatever multipliers appeared on that specific cascade, then again by the full accumulated total. That double layer, combined with a grid that keeps splitting open to 7,776 ways, is how the 10,000x cap becomes a real number. The dragon itself looms behind the reels throughout - crimson-scaled, ember-eyed, crouched over a hoard of gold coins in a volcanic cavern lit by molten orange and deep reds.
