I made a quiz game for Ruby
The backend is Ruby (postgres DB), frontend is React. If anyone sees any value here, be great to discuss ideas. Players earn reputation, unlock levels, gain badges, and climb the leaderboards by answering (and submitting) questions on Ruby.
Every question has an explanation, so you learn something regardless of whether you were correct. There is a voting and review system to ensure good quality questions.
In my opinion, polls for games are very important because each game has its disadvantages or advantages. I often see how long people choose which game to play. Recently I became interested in the casino and also couldn't choose but came across a site https://casinotop.co.nz/ where I read reviews of the casino, then asked friends and they confirmed that it is a good casino. Therefore, it is very important to do polls and read reviews before the game.
