I used to gamble, and pretty often. It sucks you in, it's horrible. And even though I placed the smallest bets, I still lost a lot. And I wasted a lot of time too. And they say, like, choose an amount you wouldn't mind losing. I'd mind losing any amount, because I earned it with my own work. Anyway, I quit casinos, but the need for something that takes up time remained, and I switched to puzzles
https://magicpuzzles.net/. Overall, I think it's the most adequate replacement for that entertainment I could find, safe, completely free, and also engaging for me.
