Curvefever 3 is a really fun game to play but in my opinion its getting boring over time.
The christmas event was kind of fun but a bit too easy etc. thats why i suggest my improvements for upcoming events 
I’ve been playing very many other online games so i might copy a bit from them by my experience
My dream event:
- Event lasts 2 weeks
- A seperate EVENT ARENA where u don’t lose any skill (like in custom games)
- Entry fee is 300 coins or 6 gems
- 6 players per game
- Arena winners get EVENT POINTS (1st gets 50 event points, 2nd gets 25 points, 3rd gets 15 points)
- Arena winners get EVENT TOKENS (1st gets 5 event tokens, 2ndgets 3 tokens, 3rd gets 1 token)
- Winners get no coins (sounds rediculas but people have to actually spend their gold and gems)
- A new EVENT LEADERBOARD (for top event point score)
- New theme based colors/ curves in a shop (which u can buy for event tokens)
- New colors, curves and titles for the TOP PLAYERS on leaderboard (so its more competitive)
- Cooldown time of some day to spend tokens (as in the Christmas Event)
- Event comes back every year at the same time so people can look forward
An event as mentioned above would raise the grinding a lot. People play to get the leaderboard place and battle for it. It’s awesome how this raises the activity and is attractive for new players too. Programming will take a bit but once the first event was up you can change the awards for the next one and keep the basics (Leaderboard refreshed, Event arena etc.)
Im always up for feedback and improvements for my suggestion. just write a comment.
Sorry for any mistakes, english isn’t my first language 
Ty a lot for reading
