Endorphina has published details for Lucky Stamps, a new slot that leans into retro emergency-service sticker collecting. The official release describes a 3x3 layout with 5 paylines, a Wild symbol, a Pile Feature, and three separate bonus games. The visual theme references 1970s and 1980s cartoon style, with Green, Red, and Blue emergency light token symbols appearing in the main game.
The headline structure is built around three emergency vehicles placed above the reels. Each vehicle maps to a different feature: the Green Ambulance opens Medic Free Games, the Red Fire Truck opens Fire Pick'Em, and the Blue Patrol Car opens Crime Hold. Endorphina states that only one of these bonus games can trigger at a time, so players encounter one mechanic per trigger rather than a combined sequence.
Medic Free Games begin with 8 free games and a 1x multiplier. During the feature, special bonus symbols can award additional free games and increase the multiplier. Endorphina notes that the maximum multiplier in this mode is unlimited, which makes the feature's progression the main variable to watch. Fire Pick'Em uses a different format: 12 flames appear on screen, each hiding one of four award symbols. The player selects flames until three matching award symbols are revealed, and that result determines the final prize.
Crime Hold moves the action to a separate 3x3 grid containing Police and Criminal symbols. Police symbols stay in position and can collect prizes from Criminal symbols. According to the release, the feature can pay regular prizes and also includes MIN, MID, MAX, and ULTRA Jackpots. The game also carries a maximum win of up to 3200x the bet.
Outside the bonus games, Lucky Stamps includes a classic Risk Game. The official description says this can double a win up to 10 times by beating the dealer's card. Endorphina also lists cross-platform availability for mobile, tablet, and desktop, and says a demo is available on its website. Andrey Oleshko, Head of Product, said the three bonus games are central to the design, with increasing multipliers in Medic Free Games called a particular highlight.
The supplied official excerpt does not include RTP, volatility, paytable values, or jurisdiction-specific availability, so those details remain unconfirmed here. What is confirmed is the 3x3, 5-payline format, the three named bonus games, the Wild and Pile Feature, the Risk Game, cross-platform support, and the stated maximum win of up to 3200x. Readers should check the official Endorphina page and local operator listings for verified technical data and availability before playing.
