Reading the figures without false hope
Each spin fills the 6x6 grid with symbols, and every cluster of five or more matching symbols that touches horizontally or vertically pays before the tumble refills the empty places. How often the bonus round arrives is not known in advance. The result of one session is random, whatever RTP version runs, so a short run can end far above or below the RTP figure.
Every spin lands on the same 6x6 grid, and the reels do not reveal which RTP version is active. The version Stake Casino runs is shown only in the game rules, so read that section before the first spin. Each version sets a different long-run return, which matters over a long series of spins, not a handful.
When WILD symbols land and add their random multipliers to the column meters, a cluster can grow far beyond its base value. The maximum win is x10,000 the bet. That ceiling is reached very rarely, so treat it as a limit, not an expectation.
