After a few rounds, it just wasn't as fun. What makes it fun to spend 10 minutes on the game is that it's the only round of the day so there's a pay-off to giving it some thought. When you can keep playing new rounds, it's just not rewarding and I would just close the tab when I was stumped.
Had I invented Wordle, I would never have thought of just one, shared round per day which is surely one of the critical elements of its success.
