Know that the top win is a ceiling
Each spin on the 5 x 6 grid lands a new set of symbols, and nothing on screen shows when the Free Games Feature or the Golden Bamboo Feature will come. How often either bonus round appears is not known in advance. One session can end far above or far below its start, because every result is random. The RTP figure only describes the long-run average.
Symbols fall on the same 5 x 6 grid whichever version runs, yet the payout percentage changes with it. Six RTP versions exist, and the one in use is shown only in the game rules. Open the rules screen in the game before you put money on a spin.
Each round can pay up to 50,000 times the Base Bet, and that multiple is a ceiling. The ceiling is reached very rarely, and no session should be built around it. Set a budget before you start.
