Slot Summary

Five reels arranged across 4 rows give Bird Jewelled room for linked Cluster Pays rather than fixed paylines. Probability Jones combines sequential symbol removal with Portal-driven reel changes and a pick-objects Bonus Game, giving the fantasy bird setting a puzzle-game cadence. The catalog lists 92% RTP and a 100000x maximum win, an unusually wide distance between theoretical return and headline ceiling.

How It Plays

Cluster Pays evaluates connected groups instead of left-to-right paylines. After a winning group clears, replacement symbols can create another cluster within the same sequence.

Portal symbols can modify portions of the reel area between results, adding a second source of change beyond the removal and replacement of winning clusters.

Theme & Atmosphere

Fantasy and Nature meet through jewel-like birds, eggs, and an enchanted setting. The subject also supports the game's matching and collection logic.

The avian presentation keeps the puzzle influence legible because birds and eggs serve as recognizable groups rather than functioning only as background decoration.

Fantasy Nature

Features & Win Potential

Cluster Pays is the core feature, rewarding connected groups and allowing cleared symbols to make space for another result in the same paid sequence.

Bonus symbols provide access to the separate Bonus Game. The base mechanic and bonus therefore use different actions: group matching first, then object selection.

Cluster Pays Bonus Game BonusGame: Pick Objects Bonus symbols

Bonus & Free Spins

The Bonus Game uses a Pick Objects format centered on eggs. Each selection reveals an award, separating the round from the base game's Cluster Pays evaluation.

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 (92.00%), with wins capped at its top multiplier (100,000×).

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.
