The Free Spins Round Shifts With Each Buy and Ante Bet

The Big Dog House puts the real choice before the first spin. Four buy options and four Ante Bet levels all reshape the same Free Spins round. Take Ghost Out and no Ghost Wild lands on reel five, so every Sticky Wild stays locked for the whole round. Take Biggie and each Wild arrives only as an Expanding Wild or one of the 3x3 Colossal Symbols. The standard round keeps both risks alive, since the Ghost Wild can remove a locked wild on any spin. Prices follow the difference: the combined round costs 500x the bet against 100x for the standard one. Every Wild carries a random 2x or 3x Multiplier, and multipliers on one line add together. The math stays Medium either way, with a 96.53% return and a 15,000x cap. What changes is where the weight of the session sits.

Game modes

The Big Dog House runs on 20 fixed paylines across a 5x3 grid. WILDs on reels 2-4 carry a random 2x or 3x multiplier each spin, and multipliers on one line add together. The modes below change WILD size, stickiness, price or trigger odds, and the maximum win is capped at 15,000x bet.

Base Game

Normal play costs a 20x bet multiplier and spins a 5x3 grid with 20 fixed paylines. WILDs land only on reels 2, 3 and 4, each drawing an independent 2x or 3x multiplier. Two or more WILDs on one payline add their multipliers instead of multiplying them.

Free Spins

Three BONUS symbols on reels 1, 3 and 5 trigger the round, or it is bought for 100x total bet. A 3x3 barrel grid reveals nine values of 1, 2 or 3, and their sum sets the spin count. WILDs become sticky at 1x1 size with locked multipliers. The round cannot retrigger.

Biggie Free Spins

This variant costs 200x total bet to buy, double the standard price. Its WILDs on reels 2-4 land only as 1x3 Expanding Wild or 3x3 Colossal Symbols, never 1x1, and stay sticky for the round. The Ghost Wild on reel 5 can still remove one sticky WILD per hit.

Ghost Out Free Spins

Bought for 200x total bet, the same price as the Biggie variant. Here sticky WILDs on reels 2-4 are permanent for the whole round. No Ghost Wild appears on reel 5, so no sticky WILD can ever be removed once it lands.

Biggie Ghost Out Free Spins

The combined round costs 500x total bet, the highest buy price of the four. WILDs on reels 2-4 land only as Expanding Wild or Colossal Symbols and remain permanently sticky. No Ghost Wild appears on reel 5, merging both modifiers in one round.

Super Spin 1

This special bet replaces normal play at a 100x bet multiplier, five times the usual 20x. Every base-game spin then guarantees at least one Expanding Wild in a random position. Free Spins cannot trigger while the mode is active.
