Bonus timing and session outcomes
On the 7x7 grid, each spin can bring BONUS chests anywhere, or none at all. How often that happens is not known in advance, and it cannot be worked out from the paytable. Two sessions with identical settings can end in very different places, because every spin is random. The RTP describes the long-run average across many players, not what one session will return.
Every spin lands symbols on the 7x7 grid, and the grid itself never shows which RTP version is running. Hunnyplay lists that detail in the game rules, so read them before comparing your results with another session. The versions differ in long-run return, which is a statement about many spins, not one.
Long free spins rounds, with retriggers and upgrades that stay in place, can carry a session toward the top prize. The maximum win is a ceiling that is reached very rarely. Hitting it depends on luck in every spin, so it is not a target to plan around.
