SPIN2U · PROVIDER GUIDES
Spin2U supports demo play, so you can learn how Booongo's Hold and Win bonus works on practice credits before you stake real money. Start small with 3 Coins, move to Dragon Pearls, try Gold Express last, then use the table to choose from all 16 BNG slots.
Booongo's bonus rounds have more moving parts than a plain line game. Symbols lock, respins count down and jackpot tiers sit on top, and the rules change from title to title. A few rounds on practice credits at Spin2U show you how a game behaves before a single real dollar is at stake.
Booongo, or BNG for short, makes online slots. Its official list has 208 released games and gives each one's reel grid, pay lines, features and jackpot tiers. Spin2U has 16 of them, and the casino supports demo play.
Hold and Win is the bonus most of these games are built on. Use your demo spins to watch these four things happen:
The number of respins, what each symbol is worth and how a Grand or Royal jackpot is won are set per game and shown in its rules screen. Read it once in demo and you will know what you are watching for.
Learn the basics on the smallest board. 3 Coins has three reels, three rows and five lines, and its classic Hold and Win respins start when three coins land. With only nine positions, you can see every lock and reset. Review sites agree on medium volatility and a 95.84% RTP.
Move up to a full 5×3 slot with 25 lines. Dragon Pearls adds a second feature, free spins with top symbols, on top of the Hold and Win respins, and lists a Grand jackpot of 1,000x the bet. In demo, practise telling the two features apart. It is rated medium volatility with an agreed 95.01% RTP.
Finish with the high-volatility pick. Gold Express runs 20 lines on 5×4 reels, has a Boost feature and power wilds in free spins, and lists a 2,000x Grand. It is the one game here that review sites agree is high volatility, so a demo session is the safest way to feel how long it can go between wins.
Aztec Fire starts on a 5×4 grid with 20 lines, but its bonus board unlocks extra rows up to 5×8. Try it in demo to see the board expand before you play it for real. Its top tier is a Royal jackpot of 10,000x the bet.
Sun of Egypt 3 has both a Bonus and a Super Bonus game, plus mystery symbols, and shares that 10,000x Royal tier. Demo play lets you see how the two stages differ, and the rules screen explains each one.
Tiger Jungle and 15 Dragon Pearls both use collect symbols, and both list a 5,000x Grand. The rules screen explains what a collect symbol gathers; a demo round lets you watch it do so.
Not every game leans on respins. Queen of the Sun gives sticky wild free spins, Wolf Saga adds giant symbols in free spins, Magic Apple has x2 wilds on 30 lines and Super Sticky Piggy builds its free spins around sticky piggy wilds and a jumping wild up to x10. Practise one of these if you prefer free spins to coin rounds.
Pick your next practice game from this table. The grid, lines, features and jackpot tiers are from Booongo's official data. RTP and volatility only appear where review sites agree; "Shown in game info" means the figure is in that game's own info panel.

When a game makes sense in demo, switching over takes a few minutes:
RTP is the share of all bets a game returns over an enormous number of spins, so no demo session, however long, will reveal it. Nine games here have an agreed figure, led by Wolf Saga at 96.06% and ending with Dragon Pearls at 95.01%. Booongo gives casinos a choice of RTP settings, which is why the same game can show a different number elsewhere. Spin2U runs each Booongo game on its default setting, the highest one Booongo supplies.
Some casino lobbies list a few of these titles under 3 Oaks rather than Booongo. If a game is not where you expect it, type its name into the Spin2U search. The 3 Oaks page covers that studio's own slots.
Deposit from AU$10 with PayID and it lands instantly; eZeeWallet, Apple Pay and Google Pay are also accepted for deposits. PayID, Skrill, Neteller and Payz withdrawals land within 5 minutes, from AU$30. The Spin2U banking guide covers each method, and the PayID guide walks you through setup.
Once you move to real money, Spin2U adds a 20% daily first-deposit bonus, and regular players can earn the AU$155.88 weekly VIP bonus. The Spin2U promotions page has the full list.
Spin2U runs in the browser on iPhone and Android with no app download, so demo and real-money play both work on your phone. The 3×3 board of 3 Coins is a comfortable size for a small screen.
Spin2U has 2,000+ casino games and supports demo play. Read our free pokies guide for more on demo mode, try 3 Oaks for more coin bonuses, or compare JILI, Playtech and Spade Gaming. The provider guide lists every studio.
Yes. Spin2U supports demo play, so you can try Booongo slots with practice credits before you deposit. Demo wins have no cash value.
3 Coins. It has just three reels, three rows and five lines, and its respins start from three coins, so you can follow every locked symbol on the screen.
No. Every spin is independent, so a demo session shows how a game plays, not what it will pay next. Use demo to learn the rules and the pace.
Yes. BNG is the short name for Booongo, so either name points to the same studio and the same 16 slots at Spin2U.
It is the top jackpot tier listed for the game, worth 10,000x the bet. It is a jackpot prize rather than a max win, which Booongo does not publish for any game here. The rules screen explains how each tier is won.
Booongo offers more than one RTP setting and each casino picks one. Spin2U runs every Booongo game on its default setting, the highest available.
The minimum deposit at Spin2U is AU$10 by PayID, and it is credited instantly.
PayID, Skrill, Neteller and Payz withdrawals land within 5 minutes. The minimum withdrawal is AU$30.
