RTP% stands for "Return to Player percentage". This is a term used in the gambling industry, particularly in online casinos and gambling games, to indicate the percentage of total wagered money that a specific game will pay back to its players over a period of time.

To put it in simpler terms, let's say a slot machine has an RTP of 96%. This means that, theoretically, for every $100 that players put into the machine, it would pay back $96. The remaining $4 would be kept by the casino as profit.

However, it's important to understand that RTP is calculated over a long period of time and a large number of games played. It does not mean that every time you wager $100, you will get $96 back. Some games you might win more, and some games you might win less or even lose. The RTP gives you a general idea of how much the game pays out compared to how much it takes in.

An advantage of knowing about RTP is that it can help you manage your spend better. By knowing how much money you can expect to lose on average, you can budget your funds accordingly and avoid overspending.
