SPIN2U · PROVIDER GUIDES
Spin2U casino has 16 Booming Games online pokies, and Spin2U supports demo play, so you can try them before you deposit. Use practice credits to learn how Hold and Win, cascades and collect features behave, then compare RTP and max win for all 16 before you play for real.
Booming bonus rounds have their own rules: coins that lock, grids that grow, collectors that gather values and multipliers that build during cascades. Reading those rules is one thing; watching them play out is quicker. Spin2U supports demo play, so you can open the Booming titles here with practice credits and see a feature in action before real money goes in.
Booming backs this up on its own website too, where every game in its official catalogue has a free demo. Practice credits have no cash value, and a good demo run doesn't predict a real-money session.
The gentlest start. It has as many as 20 pay lines on 5×3 reels, stacked symbols and a free-spins round. In demo, watch which lines pay and where the stacked symbols land. There is also an optional Gamble feature after wins; its rules screen explains the risk, so read that before you meet it with real money. RTP 96.1%, one of the five highest here. Booming publishes no max win for it, so check the game info.
The clearest Hold and Win lesson in the set. On 25 lines and 5×3 reels, landing enough coins starts the respins; coins lock where they land, and each new one keeps the round going. Fill all 15 positions and you win the 1,000x Grand Bonus. Major Free Spins, Quick Hit Bonuses and Stacked Wilds round it out. The demo lets you see how often the respin round arrives. Max win 2,000x, RTP 96%.
The next step up. The base game has 20 fixed lines on 5×3 reels, but the Ultra Hold and Win round plays on a 5×8 grid with the Ultra Reel. It also lists a Buffalo Bonus Wheel and Wild Buffalo Herd. Practice is useful here because a taller grid means more to follow. Review sites agree it is medium-high volatility. Max win 5,000x, RTP 95.6%.
In a cascade, winning symbols disappear and new ones fall in, so one spin can pay more than once. Three Booming titles here work this way, and each is worth a demo session before you spend.
Each of these four games collects values in its own way. Cash Pig has Piggy Bank coin collects on a 30-line, 5×4 window, plus free spins with Minor Elimination and Major Upgrade; it is high volatility with a 95.1% RTP. Mr. Oinkster's Hold and Win adds Piggy Bank and Vault collectors to a coin round. Fortune Surge keeps things small on a 3×3 window, with Coin Stack collects and a Surge Bonus where as many as three Collect symbols lock. Fish Tales: Double Catch uses Cash Collection and Big Net, with 10 to 20 free spins and meters for extra spins and multipliers.
Once Mustang makes sense, the other Hold and Win titles are easier to read. Buffalo Hold and Win plays like Mustang. Buffalo Hold and Win Extreme and Bonza Bucks Hold and Win Extreme 10,000 add All Coins prizes of 1x to 5x, with Grand Bonuses of 1,000x and 10,000x; that Bonza Bucks prize is a jackpot inside the bonus, and the game's max win is 12,000x. 64 Gold Coins plays on 5×5 reels with Grid Expand and Boost, and Primal Buffalo PowerGrid uses 10,000 ways with two PowerGrids that lock coins on any spin.
Bonus Buy, Blazing Bet and Oink Bet appear in some of these games as optional extras. The rules screen lists what each costs.
The RTP for all 16 and most max wins are Booming's own figures, from its demo data and press releases. Volatility and Cash Pig's max win appear only where two or more review sites agree; otherwise the cell sends you to the game's info.

Game details: Booming Games official game list ↗
A demo shows how a feature works, not what it will pay you. RTP is a long-run average across a huge number of spins, and a short demo can sit well above or below it. Booming lets each casino choose from a set of RTP settings, so the same game can return less at another site; Spin2U runs each Booming title on its default setting, the highest on offer. Across these 16 that means 96.1% at the top and 95.1% for Cash Pig, a gap of about AU$3 for every AU$300 of spins over the long run.
A max win is the most one round can pay as a multiple of the bet, so Ultra Buffalo's 5,000x at 20c is AU$1,000. Each game's rules state its limit.
Deposits start at AU$10 by PayID and land instantly; eZeeWallet, Apple Pay and Google Pay can be used to deposit as well. Withdraw by PayID, Skrill, Neteller or Payz and the money comes through within 5 minutes, with AU$30 as the minimum withdrawal. Read the Spin2U banking guide or the PayID guide for each step.
Spin2U offers a 20% daily first-deposit bonus, and VIP members can claim an AU$155.88 weekly VIP bonus. See the Spin2U promotions page for both.
Spin2U plays in the browser on iPhone and Android, with nothing to download, so demo and real-money sessions both run from your phone.
Spin2U has 2,000+ casino games. The free pokies guide covers demo play across the lobby, and Playtech, Spade Gaming, JILI and Aristocrat each have a guide. The provider guide lists them all.
Yes. Spin2U supports demo play, so you can open a Booming title with practice credits. Those credits have no cash value.
Mustang Hold and Win. It has 25 lines on 5×3 reels, and its Grand Bonus rule is simple: fill all 15 coin positions to win 1,000x. Its max win is 2,000x.
Gates of Hercules 10,000, Tasty Bonanza and Howling Wolves Megaways. The first two pay anywhere on a 6×5 grid; Howling Wolves is a Megaways game on six reels.
No. A demo shows how a feature works, but every spin is independent and RTP is a long-run average, so a short session can land far from it.

Bonza Bucks Hold and Win Extreme 10,000, at 12,000x the bet. Four games, including Burning Classics, have no published figure, so check their game info.
