UPDATE: If you enter the testingcheats true cheat on and shift + click on your Sim you’ll unlock the debug “Cheat Bowling…” option which comes with 2 options: Always Throw Tricks and Never Fail. The Always Throw Tricks option will force your Sim to perform various tricks when throwing a ball, while the Never Fail option will try to keep your ball on the lane.
If you want to level up your Sim’s Bowling Skill to Level 5 in a matter of seconds, you can do so by entering the following cheat: stats.set_skill_level Skill_Bowling [1-5] (add a skill level from number 1 to 5 instead of the brackets). Make sure you’ve entered the testingcheats true cheat first!
