Big Bamboo is an Asian-themed online slot from Push Gaming set in a tranquil bamboo forest. The game features a 5×6 grid with 50 paylines. Symbols on the reels include card suits (clubs, diamonds, hearts, spades) as the low pays, along with premium animal symbols like a bird, monkey, boar, and a panda which is the highest-paying regular symbol.
The base game revolves around the Mystery Bamboo feature. Mystery Bamboo symbols can land anywhere and reveal either regular pay symbols or special Golden Bamboo symbols. When Golden Bamboo symbols are revealed, they trigger a bonus reaction where each position spins individually to reveal instant cash prizes, multipliers, or bonus symbols.
Instant Prize symbols award a cash prize of 1x to 5,000x the bet. Multiplier symbols (2x, 3x, 5x or 10x) multiply the values of any instant prizes in view. Collector symbols gather all instant prize values and can remain sticky to collect over multiple spins. The maximum win of 50,000x is possible by combining a 5,000x coin with a 10x multiplier.
Scatter and Gamble Scatter symbols can also appear to trigger the Free Spins bonus. In the base game, 3 scatters (on reels 2, 3 and 4) award 7-10 free spins. Before starting, players can gamble for a higher number of spins or extra Mystery Bamboo symbols.
In the Free Spins, low paying symbols are gradually collected and converted into Mystery Bamboo symbols, increasing their frequency. Each tier of symbol collection also awards additional free spins (up to 12 extra in total) and increases a global multiplier that applies to any Golden Bamboo prizes.
The slot is highly volatile, with an RTP of 96.13%. Betting ranges from £0.10 to £100 per spin. For an additional cost, players in some jurisdictions can use the Bonus Buy feature to purchase free spins with a varying number of symbol conversions.
