Quick verdict: Bonanza Megapays is Big Time Gaming’s June 2021 remake of its gold-mining Megaways hit, with four progressive jackpots added through the Megapays system. The reels, reactions and unlimited free spins multiplier are the same idea as the original; the difference is a random jackpot feature that can land on any spin. The RTP is 96.40%, but roughly 9.5% of that goes to the jackpots.

How the reels work
- Six Megaways reels show 2 to 7 symbols each, and a horizontal top reel with 4 mine carts sits above reels 2 to 5, for up to 117,649 ways.
- Winning symbols are removed and replaced from above and from the carts. These reactions continue until no new wins form.
- The dynamite wild only lands on the top reel and stands in for every paying symbol except the scatters.
Free spins
- Land the four scatters that spell G-O-L-D for 12 free spins. Each extra scatter in the trigger adds 5 more.
- The multiplier starts at 1x and rises by 1 with every reaction. It never resets during the round and has no limit.
- 3 or 4 retrigger symbols during the round add 5 or 10 more spins.
The Megapays jackpots
The jackpot feature starts at random after a spin. One symbol is chosen, and on a 6×7 grid only that symbol counts: each one that lands locks in place and gives another respin. The feature ends when no new symbols land, and the number you collect decides the prize.
| Jackpot | Symbols needed | Starting value |
|---|---|---|
| Mini | 4 to 7 | 100 |
| Midi | 8 to 11 | 1,500 |
| Major | 12 to 14 | 20,000 |
| Mega | 15 or more | 300,000 |
Starting values are in pounds or euros depending on the market. The four jackpots are shared by every game linked to Megapays.

Bonanza or Bonanza Megapays?
The original Bonanza is the game that started the Megaways format, with no jackpots. Megapays keeps the same reels and free spins but takes about 9.5% of the RTP for the shared jackpots, so the regular game pays back roughly 87%. Pick Megapays if you want a jackpot chance on every spin, and the original if you would rather have that RTP in the regular game. For more from the studio, see Extra Chilli Megaways, Who Wants to Be a Millionaire Megaways or our Megaways slots.
