Verdict

Bonanza is Big Time Gaming's mining-themed slot from 2017, playing out on a six-reel, five-row grid stacked well above the usual three-or-four-row board, with gem and letter symbols filling the space and a loaded wooden cart sitting beside it.

The 96% RTP is about what most slots run. Play it if you want a look at an older, straightforward Big Time Gaming release without much noise around it. Skip it if you'd rather have a fuller feature list to dig into first.

Screenshots

Gem symbols in purple, red, blue and green line up alongside the A, G, Q and K letter tiles across the tall six-by-five board, with the mine cart and cottage framing the scene.

How it plays

The reels run six wide by five deep, giving the board an unusually tall, busy look next to a standard grid. Gem symbols in purple, red, blue and green sit alongside card-style letter tiles for A, G, Q and K, all set against a mine backdrop with a loaded wooden cart and a small cottage in the background. It's a straightforward, symbol-heavy board built around that mining scene, with nothing else confirmed about how a spin plays out from here.

Who it's for

Suited to players who already like Big Time Gaming's catalogue and want to see one of the studio's earlier, simpler releases for free before moving on to its later games.
