Push Gaming · 2022
Push Gaming's 5x6 Chinese jungle video slot on 50 fixed lines, from RTP versions to reels and free spins. Figures first, then the play.
Choose Big Bamboo if you want a Chinese-themed slot with pandas, monkeys and wild boars on a 5x6 grid. The base game uses 50 fixed win lines, and each line pays only its highest win. A win needs as few as two matching symbols. The four card-suit symbols are the low symbols that feed the free games, where a fully converted low symbol adds spins and a multiplier.
Pick Big Bamboo if you want the round to change as it goes. Free games start when enough Scatter or Gamble Scatter symbols land on reels 2 to 4. A meter tracks the card-suit symbols, and each full conversion adds spins and a multiplier. A Mystery Bamboo can uncover a Golden Bamboo, which starts a respin. A losing gamble forfeits the free spins.

Clear Path to Payouts
This block settles what your bet does, how wins form, and when the bonus starts.
Pick a bet from A$0.10 up to A$100 before the reels start. The Base Bet you choose multiplies every win, so a bigger stake scales each payout.
Check the 50 fixed win lines on the 5x6 grid before you read a result. Each line pays only its highest win, so a line never adds up several prizes.
Look for Wild symbols and Mystery Bamboo reveals on each base spin. When one uncovers Golden Bamboo, a respin starts with Instant Prize and Collector symbols.
Watch reels 2 to 4 for Scatter, BONUS and Gamble Scatter symbols. Enough of them trigger a set of free spins, and nobody can know in advance when that lands.
Set your limit before the first spin and decide when you stop. If play stops being fun, call the National Gambling Helpline on 1800 858 858.
Stronger payouts
Here is where each bonus starts, what happens inside it, and where you make a choice.
Start by landing enough Scatter, BONUS and Gamble Scatter symbols on reels 2-4 to get a set of free spins and a Low-Symbol conversion meter. Each time a low symbol fully converts to bamboo, the meter adds bonus spins and a multiplier. More scatter landings retrigger extra spins.
Base gameFree spins
Watch for a Mystery Bamboo reveal symbol that uncovers a Golden Bamboo underneath. Each Golden Bamboo position spins through Instant Prize, Multiplier, Scatter, Gamble Scatter and Collector symbols until resolved. Instant Prize and Collector values are summed and multiplied by the Base Bet. Any landed multiplier applies too.

Decide after a Free Spins trigger whether to collect or gamble. The Gamble Feature shows a vertical prize ladder with the awarded tier highlighted. Collect the current award, or gamble it for a chance at a higher ladder tier. A losing rung forfeits the free spins entirely.

Choose a bonus option on the shared Base Bet stepper. The four options are no low symbols converted, 2 low symbols converted, 4 low symbols converted with no gamble step, and Mystery Free Spins. Mystery Free Spins randomly resolves into one of the other three outcomes.

Three Screens Below
Useful when you want to see a win or free spins screen before you decide to play.
Two paths
Rainbet keeps practice and real play clearly apart, so you always know which one you're on.
The demo needs no money and pays nothing, so it shows the mechanics only. Real play needs a Rainbet account and you must be 18 or older.
Start playingNobody knows when the free spins will turn up. The bonus round can arrive on your second spin or not at all in a long session, and one session's result stays random whatever return the game carries. High volatility means long quiet stretches sit alongside the big ones, so treat any sitting as one you can walk away from.
Which of the listed versions you are playing is written in the game rules screen, opened from the info button on the grid. Check it there rather than assuming the highest figure applies, because the difference compounds over hours of spins at the same stake.
The x50,000 top is a ceiling, not a target. Reaching it at A$0.40 would mean A$20,000, and the same multiple at A$5 lands at A$250,000. Prizes that size stay rare across any run of spins, so keep an ordinary session's expectation separate from the headline figure.

Slot Snapshot
Settle the key numbers and rules before you place your first spin.
This version sits lowest in the series at 96.13% RTP and carries a x50,000 cap. Later releases push the cap to x75,000, x25,000 and x75,000 again. The grid, themes and features are shared across the family.
Yes, Big Bamboo opens in demo mode at Rainbet Casino, so you can spin the reels without staking anything. The play money version runs the same grid, lines and feature rules. Switch to real money whenever you feel ready.
Big Bamboo carries six RTP settings that range from 96.13% to 96.94%, with 96.71% and 96.76% sitting mid-range. Which one applies to your session is drawn at launch, not chosen by you. Check the paytable for the active figure.
Big Bamboo caps a single round at x50,000 the base bet, so a A$0.40 stake tops out at A$20,000. At the A$5 example bet the ceiling is A$250,000, and at the A$100 maximum bet it reaches A$5,000,000.
Stakes on Big Bamboo begin at A$0.10 and run to A$100 per spin. The A$0.40, A$2 and A$5 figures on this page are examples only, set aside for the paytable and the cost tables. Pick any amount inside the real range.
Rainbet Casino is for players aged 18 and over. In Australia, call the National Gambling Helpline on 1800 858 858, and sign up to BetStop, the national self-exclusion register.
Decide what Big Bamboo gets tonight and treat that figure as spent once you sit down. Keep it separate from rent, bills and money you owe.
Pick a winning point and a losing point before you start, and log off at whichever arrives first. A big win is a fine place to finish, not a reason to chase another.
Set a deposit limit and a loss limit in your account and leave them where they are. The 50,000x cap on Big Bamboo stays out of reach for most sessions, so the limits are what protect the week.
If Big Bamboo starts feeling like a task rather than a pastime, take a break from the lobby and come back another day. A self-exclusion through BetStop shuts the door properly when a pause is not enough.
