Chicken Drop keeps its biggest multiplier out of reach
Chests drop onto the grid at random, and nothing on screen tells you when the next bonus round will come. How often that happens is not known in advance. The result of one session is random whatever the RTP, so a long run of quiet spins says nothing about the next one.
Each spin of the grid is paid out under one of two RTP versions, and the game rules name which one is live. Which version Palmerbet runs is shown only in those rules, so read them before your first spin. Over a short session the gap between the two will not show in any reliable way.
Clusters grow and tumble until the reels settle, and the top multiplier of Chicken Drop is a ceiling that very few rounds reach. The maximum win is a limit, not a target, so a big session and a small one can both end far from it. Set a budget before the first spin and stick to it.
