Charge Spots feed the Collector on a 5×6 grid

Bonus keeps charges between spins until collection; Super Bonus keeps them after. Listed RTP builds span 94.06%–96.18% with a 10,000× ceiling.

How Junk Punk rules and features work

Bonus features

Attached splash frames state that three battery symbols open Bonus and four open Super Bonus. In Bonus, Charge Spots stay between spins until a Collector converts them into Energy Cores. In Super Bonus, charges can remain after collection. Feature Selection frames at the loaded demo stake show preview prices for Chance Enhancer, Guaranteed Collector, Bonus and Super Bonus; those amounts are stake-linked demo figures, not universal cash prices.

How to play Junk Punk responsibly

Set a money limit and a time limit before spinning. Count every feature cost against that budget immediately and do not raise stakes after a quiet stretch.

Junk Punk RTP, volatility and maximum win

The card stores 96.18% as the displayed RTP and the top of the published range; rtp_text lists 96.18% / 94.06%. Those values describe published builds, not a short-session return.

Junk Punk compared with other games

Other Happy Duck cascade cards also clear winning symbols and refill the grid, but shared branding does not copy Charge Spot persistence. Compare Bonus versus Super Bonus rules, Collector timing, the listed 94.06%–96.18% RTP band and the 10,000× ceiling before treating another scrapyard theme as interchangeable.
