SLOT SESSION // 1,500 SPINS
At Peter & Sons's declared 96.6%, a run of 1,500 spins at this bet averages out around -51× stake, shown as the dashed line. This one ended at -86.6×, about 1.7× further down than the average run. One session swings hard either way; the gap is the swing, not the game's payout rate.
The driest stretch ran 27 spins without a single win, spins 225 to 251.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -125.3× the stake, while 2 finished in profit, the best at +311.9×. These are consecutive blocks of one continuous session, not 10 separate sittings: the balance never reset. Block 1 was played through the game's own interface; the rest replayed the bet call directly. Same numbers either way; only the first can be photographed.
Our review of Bubblegum and Robo
I spent October 2026 testing Bubblegum and Robo from Peter & Sons, and this Bubblegum and Robo review is based on 10 separate sessions, 1,500 spins in total, all at a flat 2.00 bet. The short version: I can't recommend it, and even high-volatility fans should think twice. Across the whole run the game returned 94.2% against a stated RTP of 96.60%, and my best single win was 236.6x.
Each session was a fresh launch of the game with its own balance, about 150 spins each, and the numbers below are all 10 sessions added up. Every spin ran in the game's free mode, so no real money was on the line.
One recorded run of 1,500 spins is not a measurement of the slot's payout rate; that only settles over tens of thousands of spins.
The game is labeled high volatility, and nothing in the run argued with it. Wins landed on 21.3% of spins. The longest stretch without any win at all ran 27 spins, and the deepest hole I sat in was a 299x drawdown.
The 4 hits of 100x or better were the only moments the balance got to breathe. Even the best of them, 236.6x, never came close to the advertised 20,000x ceiling, and it wasn't enough to pull the run out of the red: the whole thing closed at -87x the stake. That's the part that wore me down. A high-volatility slot asks you to sit through dry spells for a shot at something big, and here the dry spells showed up right on schedule while the something big never did.
Pros
Cons
If you still want to try it, this is strictly a high-volatility game for someone who can sit through a 299x drawdown and a longest dry run of 27 spins without flinching. A deep bankroll buys you the seat through swings like that; it doesn't change what the slot gives back, and in my run it gave back 94.2%.
Everyone else should skip it: two winning sessions out of 10, a top hit of 236.6x against an advertised 20,000x ceiling, and a final balance of -87x the stake. I give it a 3/10: the stated 96.60% RTP reads fine on paper, but my run came in below it at 94.2%. Another 1,500 spins could look different, of course. I can only report what mine looked like, and mine was a grind that never paid off.

Bubblegum and Robo combines Steampunk machinery with cartoon robotics. Peter & Sons presents this September 2025 release, delivering a 5x5 grid slot that leans heavily into volatility and wild-driven mechanics.
The action unfolds on a fixed 5x5 grid where wins form through matching symbols across the reels. Wild symbols substitute for regular symbols, while Expanding Wilds can stretch to cover entire reels. Sticky Wilds anchor themselves in place for subsequent spins. Multipliers increase the value of wins.
Scatters count wherever they land; Free Spins run without further stakes. The Buy Bonus option lets players pay to enter the bonus directly. Ante Bet raises the stake in exchange for better feature odds.
The 96.60% RTP sits above the 96% industry benchmark. High volatility means sessions trend toward longer dry spells punctuated by substantial hits — this profile favors patient bankroll management and players comfortable with variance. The 20,000x max win places the game in high-potential territory.
Steampunk, Robots, and Cartoon theming combine for an aesthetic that feels mechanically whimsical rather than grimdark. The cartoon treatment keeps the atmosphere light despite the high-volatility math underneath.
Bubblegum and Robo earns its 7/10 rating. The wild-heavy feature set plays well together, the RTP is genuinely above average, and the 20,000x ceiling is high. The high volatility will filter out casual players. Try the free demo to see if the rhythm suits your style.
