II89 · PROVIDER GUIDES
ii89 online casino has 16 Booming Games pokies, and most fall into one of four themes: animals, coins and gold, classics, or myth, candy and fishing. Pick the group you like, see how each game in it plays, then compare RTP and max win across all 16 in one table.
If you already know the kind of game you like the sound of, start from the group below. Each title appears once, and the sections further down explain how each one plays.
From the animal group, and the only Megaways game of the 16. It is a Megaways slot on six reels, which means the reel heights change on each spin and so does the number of ways to win. Winning symbols cascade out to make room for new ones. Booming lists Howling Wilds, an Alpha Wolf Spin, Wolf Pack Multipliers and Free Spins as its features. RTP 96%; the max win is in the game info.
From the coins group, and the only one of the 16 on 5×5 reels, with 30 pay lines. Its coin round adds Grid Expand and Boost, there are Flaming Respins and a Collection Pot, and an optional Blazing Bet whose cost the rules screen shows. The max win is 10,000x the bet, which is AU$5,000 at 50c a spin, and the RTP is 95.9%.
From the candy group. Symbols pay anywhere on a 6×5 grid rather than along lines, and wins cascade with Random Multipliers. A Candy Jar collector, bomb symbols and a free-spins round with no fixed limit on spins round it out. Review sites agree it is high volatility, so expect long quiet stretches between bigger hits. Max win 6,500x, RTP 96.1%.
Buffalo Hold and Win is the base version: 25 lines on 5×3 reels, Hold and Win coins with a Grand Bonus, Major Free Spins, Quick Hit Bonuses and Stacked Wilds, and a 95.9% RTP. The Extreme edition keeps the 25 lines and adds All Coins prizes of 1x to 5x, a 1,000x Grand Bonus, Bonus Buy and a 4,000x max win. Ultra Buffalo uses 20 fixed lines, then takes its bonus to a 5×8 grid with the Ultra Reel; it is rated medium-high and tops out at 5,000x. Primal Buffalo PowerGrid drops lines for 10,000 ways on a 4-5-5-5-5-4 grid, with two PowerGrids that lock coins on any spin and a 2,150x max win.
Mustang Hold and Win shares the original Buffalo's 25-line layout and features. Its Grand Bonus rule is clear: fill all 15 coin positions to win the 1,000x prize. Cash Pig has 30 lines on 5×4 reels, Piggy Bank coin collects and free spins with Minor Elimination and Major Upgrade; it is rated high volatility and has the lowest RTP of the 16 at 95.1%. Mr. Oinkster's Hold and Win runs 20 lines with Piggy Bank and Vault collectors, Jumbo Symbols in free spins and an optional Oink Bet, with a 2,000x max win.
Gold in the title doesn't mean the games play alike. Fortune Surge is the smallest of the 16, a 3×3 game with 5 fixed lines, Coin Stack collects and a Surge Bonus in which as many as three Collect symbols lock. Gold Gold Gold is a plain five-reeler with as many as 20 lines, stacked symbols, free spins and an optional Gamble feature. Bonza Bucks Hold and Win Extreme 10,000 brings All Coins prizes and Bonus Buy; the 10,000 in its name is its Grand Bonus, and its max win is 12,000x.
The one classic title in the set uses the same frame as Gold Gold Gold: as many as 20 lines on five reels and three rows, stacked symbols, free spins and an optional Gamble step. Its 96.1% RTP is one of the five highest. Booming publishes no max win for it.
Gates of Hercules 10,000 shares Tasty Bonanza's pay-anywhere 6×5 grid, with 8 or more matching symbols needed for a win. Wins cascade, random multipliers from 2x to 500x can drop in, and 15 free spins come with a growing multiplier and Boost+. Max win 10,000x, RTP 95.9%. Fish Tales: Double Catch goes back to 10 lines on 5×3 reels, with Barrel Boost, Cash Collection and Big Net, and 10 to 20 free spins with extra-spin and multiplier meters. It also reaches 10,000x, at 96.1%.
Booming's own demo data and press releases give the RTP for all 16 and most max wins. The four volatility ratings, and Cash Pig's max win, are where two or more review sites agree. "Shown in game info" points you to the game's own info panel.

Game details: Booming Games official game list ↗
No. The animal group alone runs from Cash Pig's 95.1% RTP to Primal Buffalo's 96.1%, and from 2,000x max wins to 5,000x. Pick a theme for what you enjoy looking at, then compare RTP and max win in the table. RTP is the long-run share of stakes a game pays back; on AU$200 of spins, a one-point gap is about AU$2.
Booming offers casinos a choice of RTP settings, so the same title can return a different figure elsewhere. ii89 runs each Booming game on its default setting, the highest available.
Booming's official catalogue holds 118 games, 117 of them slots, and the studio hosts a free demo of each on its website. Every game's rules give its max win limit as a multiple of the bet. The 16 above are part of 6,000+ casino games at ii89.
ii89 supports demo play, so you can open a buffalo game and a candy game side by side with practice credits. Practice wins can't be withdrawn, and demo results don't predict real-money spins. See the free pokies guide for how it works.
PayID deposits from AU$10 are instant, and you can also deposit with eZeeWallet, Apple Pay or Google Pay. Withdrawals by PayID, Skrill, Neteller or Payz arrive within 5 minutes, and the minimum is AU$30. The banking page and the PayID page have the details.
ii89 runs an AU$59.88 daily VIP bonus for VIP members and a 30% Sunday bonus. Find both on the ii89 promotions page.
The ii89 site works in your phone's browser on iPhone and Android, so no app download is needed.
For more themed pokies, try Booongo, JDB or Pragmatic Play. JILI and Aristocrat are also in the lobby, and the ii89 provider guide lists every studio.
Eight: four Buffalo games (Buffalo Hold and Win, the Extreme edition, Ultra Buffalo and Primal Buffalo PowerGrid), plus Mustang Hold and Win, Howling Wolves Megaways, Cash Pig and Mr. Oinkster's Hold and Win.
The original and Extreme both use 25 lines on 5×3 reels; Extreme adds All Coins prizes and a 4,000x max win. Ultra Buffalo has 20 lines and a 5×8 bonus grid, and Primal Buffalo PowerGrid uses 10,000 ways.
Bonza Bucks Hold and Win Extreme 10,000, at 12,000x the bet. 64 Gold Coins Hold and Win follows at 10,000x.
