Dragon Born Slot by Big Time Gaming

This is where Megaways began. Big Time Gaming built the engine here in 2016, before Bonanza turned the six-reel variable-height format into a household name. So it plays a little like a museum piece. There are no tumbling reactions, none of the cascade chains people now expect from Megaways, every spin resolves once and pays. The reels only shuffle their heights, two to seven symbols apiece, and the ways count rises and falls with them, up to 117,649 at full stretch.

The world is a misty mountain kingdom: snow-capped peaks, a river threading through green valley fields, a low golden sunset behind it all. Symbols run heraldic. A snarling red dragon head is the top premium, and it's greedy by old standards, paying from just two matching on a line where the crests and banner need three. Red and blue jewelled crests and a green fleur-de-lis banner fill out the rest.

The Full Reel Wild does the heavy lifting. Up to two can land on a spin, and each covers a whole reel, counting as a stack of up to seven icons and standing in for everything but the Diamond. Each one also carries a multiplier of up to x7, built straight into the reel. Land both inside the same win and the multipliers don't add, they multiply, so two maxed reels drag a combination to x49. A full column of seven also swells the ways total while it sits there, feeding every path behind it.

Diamonds are the Scatter. Three open the free spins at 6, four at 12, five at 25, six at 50, and every Diamond that lands during the round adds another spin, up to five a time, with no ceiling on retriggers. Single and stacked Wilds keep substituting in there. Any win, base or bonus, lights a Gamble button for a double-or-nothing on the payout, and if you'd rather not wait for three Diamonds, the buy option drops you into the feature directly, with Feature Drop symbols knocking down the price.
