The power forward added 31 in the 109-102 victory over the Los Angeles Lakers, including a 20-foot effort inside the final minute of the game which effectively sealed the win.
The 29-year-old told reporters: "I like it. It's fun, especially when they're going in. If you go eight for 20, that's no fun. But when the shots are falling and teammates are looking for me, it's a good feeling."
Bosh scored on 15 of his 22 efforts from the field, including all five inside the final quarter.
