The game we have is the summer reskinned, and as someone who loves the mini-games one of my least favourite, but I appreciate that you want to balance the intensity of them! I know the card game mechanics for the fellowship were very slow, but maybe there is a place to bring the game back in a faster way? The illustrations and animations were very beautiful for the Halloween version.
The game we have looks really well, and I think the daily challenges are a really positive addition to motivate daily engagement (I know for summer I used to just save up coins and play all in one go). I also really like skipping the animation option of it. The three tubes is a fun idea, although might it be better to spread the tokens out more? e.g. 1 for the green circles, and maybe only 3 on the larger prizes. I'm not sure how the rebalance would work, but I think it might be a nicer motivator.
The one thing I think does need to be fixed is the diamond costs for more tickets - 200 for 2400 diamonds seems far too steep to me. I think either add more tickets for that price, or reduce it to be one of those 1050 diamonds for the highest purchase, and drop the tickets to like 150? As a big minigame fan, I often spend diamonds to play more, but I just can't see many purchasing them for that price, unfortunately.
