The standard RTP (Return to Player) for 777 Rainbow Respins slot is 96.1% (Could be lower on some sites). This payback is good and considered to be about average for an online slot.

However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 6500x your total bet which is pretty high and gives you the chance to win quite big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
