How to cite

Slot Summary

Start a spin, then follow how far the reels extend toward the waiting book in Book of Ultimate Infinity Reels. Red7 connects Egyptian book-slot conventions with ReelPlay's expanding-reel mechanic, turning access to free spins into a question of distance reached during a round. The book is a destination along the expanding field, giving the treasure-search setting a concrete mechanical purpose.

How It Plays

The reel field extends to the right when the Infinity Reels mechanic continues a winning sequence. An added reel also raises the multiplier, linking the sequence's length to its eventual payout.

Wilds help complete qualifying combinations as the field extends. When a new reel does not continue the sequence, the expansion ends and the game returns to its starting reel configuration.

Bonus & Free Spins

The book waits at a randomly selected position between reels 6 and 15. Reaching that position awards 10 free spins and selects a special symbol that can expand across entire reels.

The selected symbol expands when it appears on at least two reels. During the bonus, its appearance on the rightmost reel can also add another reel even without improving the existing winning combination.

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 (High). The model is calibrated so the average return equals this slot's published RTP (96.50%), with wins capped at its top multiplier (5,000×).

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.
