Rainbow Jackpots series

Rainbow Jackpots set the baseline in 2017 with a 5x3 grid, 20 paylines, high volatility and a 1,054x maximum win. Rainbow Jackpots Power Lines narrowed the game to four listed lines in 2020, then used symbol swaps and a pick-object bonus to create more feature dependence. Its 1,224.90x ceiling is only a modest increase, so this sequel changes the route to a payout more than its scale.

Where the formula breaks away

1. Rainbow Jackpots Megaways: the Megaways entry expands to a 6x7 layout with up to 117,649 ways, cascades, random multipliers, extra wilds, bonus buying and a 20,000x maximum win.
2. Rainbow Jackpots Tap-A-Roo: Tap-A-Roo returns to a 5x3 frame but redirects the series toward tap-game interaction, supported by free spins and random multipliers.

The practical choice is between engines, not themes. The original supplies the clearest fixed-line version, Power Lines concentrates value into fewer lines and bonus events, Megaways raises both mechanical density and payout ceiling, and Tap-A-Roo changes how the player interacts with the familiar rainbow package.
