You're facing a mathematical psycho killer who is forcing you to choose from ten chambers, each containing a button labeled with a distinct digit from 0 to 9. The button will glow for a moment according to the digit order of pi, starting from 3, 1, 4, and so on. If any button glows for 7 times, the equipped bomb will be triggered and completely destroy that chamber while the next number moves on.
The mathematician killer is ironically merciful enough to automatically defuse the last bomb if the previous 9 bombs blow up.
If you want to stay alive from this game, which chamber number should you choose?
