These games need to load their bonus and features into memory and if you don’t have enough space it can freeze on a mobile or if your internet speed is slow it can take a while, some bonuses need 80mb of data
Things to try:
* different browser
* different platform – eg, mobile or pc
* incognito mode
From doing a post on the blueprint games, i know that the bonus you choose will still be stored, as they keep a track of it all in the responses, if you are familiar with computers you can go into developer tools on chrome and see where the errors are
