Like @jan duchau said, to spice things up based on @Blackjax idea. lets do monthly contest with 3 latest releases to expose the slots and review them.
however for the core suggestion : we do appreciate the contest and you can bring them whenever you want.
from a finance perspective, I would have a slighter smaller prize pool like 1200 euro on a monthly basis, with guaranteed contest every month until December. How these run with different games or how it can spice things up.
But my suggestion is to secure a contest every month, with a smaller prize pool as a sacrifice and we can on a monthly basis decide rules for each contest in terms of game selection, latest releases, a specific game etc. but main thing is to try have a contest monthly (hence the reduce prize pool. if its possible )
