Final Thoughts on RTP

You should know that the 99% RTP is only available in big bet Mode. This means that in order to play with the 99% RTP, you must bet the maximum amount of £5 per spin. Ugga Bugga remains an utterly unique slot due to its unique reels and rows which are called ‘held reels’.

So, for every £100 you put into the slot, you will get back £99.00 in theory.

Since RTP configurations can vary by casino, market and jurisdiction, we strongly recommend checking the in-game info screen at your chosen operator before you spend any real money.
