Effective Altruist Opportunity: Spin For Good is running a $1000 money added online blackjack tournament this week that’s 100% for charity. I’m currently one of the leaders but I’d definitely welcome some friendly competition.
It only costs $10 to enter and if you’re one of the top finishers, your charity wins a chunk of the full prize pool. Worst case, your $10 goes to charity. Best case, you get a high enough score to help pick which charities gets more of the money in the prize pool.
You can play for lots of great GWWC-recommended EA charities like: Against Malaria Foundation (AMF), Project Healthy Children (PHC), Schistosomiasis Control Initiative (SCI), etc.
