Bigger Barn House Bonanza

Bigger Barn House Bonanza is the second entry in the series, running on a 5x3, 243-ways base grid that can expand to 5x6 (7,776 ways) during the Super Wheel Bonus. 96.50% RTP, high volatility, 25,000x maximum win. The step up from the original Barn House Bonanza is real — higher ceiling, higher volatility, and a Super Wheel Bonus tier that the original lacks.

The bonus triggers on 6+ scatter symbols, awarding 6 free spins with marked positions that upgrade straw-to-wood-to-brick. After free spins, positions reveal prizes at their current tier. The Wheel Bonus activates via base-game Wheel symbols or in-bonus random triggers; the Super Wheel Bonus is the new addition — it expands the grid and applies pre-marked positions to the wider layout, concentrating the prize-reveal event across more cells. The Super Jackpot (25,000x) is the grid-fill event on the expanded layout.

High volatility means the base game is quieter than the medium-volatility Better Barn House Bonanza. Free spins trigger roughly once every 70-75 spins, which is frequent for high volatility. The 25,000x ceiling is real but lottery-grade in terms of probability. The realistic session range sits in the 10-200x band on most bonus triggers.

Against Better Barn House Bonanza (96.50% RTP, 35,000x, medium volatility): Better outranks Bigger on ceiling at lower variance, which is an unusual inversion. Against Brick House Bonanza (96.50% RTP, 10,000x, medium-high volatility): Bigger improves the ceiling substantially. Choose Bigger for higher volatility and a legitimate 25,000x ceiling; choose Better for an even higher ceiling at medium variance.

Verdict
The high-volatility Barn House entry. Grid expands during the Super Wheel Bonus, 25,000x ceiling. Ceiling is lower than Better Barn House — an unusual series oddity.
