Double Bubble at a Glance

Symbol Payouts, Volatility and Return to Player

The paytable in Double Bubble follows a classic structure, rewarding combinations of matching icons across active paylines. Below is a breakdown of what each character pays for landing five of a kind on a single line. With an RTP of 97.87%, Double Bubble sits well above the industry average of around 96%. Its low-to-medium volatility means wins arrive with reasonable frequency, though they tend to be modest in size. This balance suits users who prefer longer sessions over chasing large but rare payouts. The 500× maximum win keeps the ceiling accessible without the extreme swings associated with high-volatility titles.

The Double Bubble Free Spins Round

Landing three or more bubble scatter icons anywhere on the reels triggers the free spins feature. The number of spins awarded depends on how many scatters appear at once.

1. 3 Scatters — 10 free spins
2. 4 Scatters — 15 free spins
3. 5 Scatters — 20 free spins

During the free spins round, a second set of reels activates below the main grid. This lower set runs simultaneously and gives gamblers an additional chance to form winning combinations without placing an extra wager. Both grids share the same wild and scatter rules, which effectively doubles the number of opportunities on every spin.

The Double Bubble Mechanic

The defining feature of this title at casino Mr Luck is the dual-reel system. While most fruit machines operate on a single grid, this one runs two grids at the same time during bonus play. The lower reel set mirrors the layout of the upper one but spins independently, producing its own results. This mechanic sets the activity apart from standard five-reel slots and gives it a distinctly British identity rooted in the pub gaming culture that Roxor Gaming was built around.
