Yeah, best do what I'd do, and stay away from any suspicious-looking recruiters at railway stations

!
Though, it's a shame I'd probably die in the first game - because I think I'd be better at some of the later ones:
Sugar Honeycombs - Without knowing the game in advance, I'd probably pick an umbrella (thinking I might get one to protect me), so this wouldn't be easy. However, I do have experience of drawing and railway modelling, both of which require precision with one's hands - so that would be very helpful.
Night Riots - I'd be useless in a fight

. I'd probably just hide, and hope for the best.
Tug of War - Another one where I probably wouldn't be much good

. Let's hope I have a good team!
Marbles - I might actually be better at this one. As a mathematician, I might be able to trick my opponent by inventing a game based on something like the
Monty Hall problem... if I set it up correctly, I could give myself a 2/3 chance of winning each round

.
Glass Bridge - Probably the one I'd be the most confident of beating. Without knowing the game in advance, I would've picked number 13 (since it's my favourite number: it's the day I was born

). According to
this graph (from
this page), player 13 has a 95.2% chance of surviving the game (assuming, of course, that you don't run out of time, and no players ahead of you waste their lives by getting pushed off without going through a panel!)
Squid Game - I might have a decent chance of this

. Most Westerners don't seem to know the rules of this game (even if they've watched the show) - but I at least have a vague idea of how it's supposed to work. If my opponent was another Westerner (who didn't know the rules), then I'd have an advantage... but, if I was playing a Korean who grew up with the game, then I'd be in trouble

.
(Although, in reality, I would've voted to leave if I got the chance, and then not come back!!!)
