Slot Summary

Pin-Up fills the space between a plain 10-line slot and a more elaborate feature game by adding Expanding Symbols, Free Spins, and a post-win gamble option to a 5x3 format. Endorphina uses Retro car and Luxury imagery to give those familiar mechanics a specific period identity. The unusually low 90.04% RTP is the most consequential number for comparison, despite the accessible 0.01 minimum bet.

How It Plays

Regular outcomes use 10 paylines across a 5x3 reelset. Wild Symbols help complete line combinations, while Scatter Symbols provide the route into Free Spins.

After an eligible win, the Risk/Gamble game creates a separate decision: accept the calculated award or place it at risk through the optional double game.

Theme & Atmosphere

Retro defines the period treatment, while Car and Luxury supply its central objects. The result recalls polished advertising imagery rather than a contemporary road setting.

The Pin-Up subject connects glamour and automotive design, giving a straightforward payline game a recognizable mid-century commercial style without changing its core rules.

Retro Car Luxury

Features & Win Potential

Expanding Symbols increase their reel coverage when activated, creating a different path to line combinations from the ordinary single-position Wild Symbol.

The Risk/Gamble game sits after qualifying wins, separating its double-or-lose decision from the reel outcome that produced the original award.

Bonus & Free Spins

Scatter Symbols trigger the Free Spins route, where Expanding Symbols become the key change from ordinary paid play and can cover additional reel positions.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (90.04%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
