Roulette

Bet Ryo or Items. No refunds. Spin the wheel when you are ready!

On an 11, every bet wins!

Math

Like a real roulette, on average you will lose a slight amount of money. Since the best ROI is 25/26 of your bet. Bet on the number 11 ten thousand times for 1000 ryo a bet (total 10 million bet) and you will get back 10,000,000*25/26 = 9,615,385 ryo on average.
It is thus best to only play the roulette if you are trying to get Yuki-chan or the trophy.

Ally

Winning 1,000,001 or more Ryo also wins you Yuki-chan.

As they deliver you a sack of over one million Ryo, a girl runs up to you! "Oh my goodness, you shouldn't have bet so much here! Gambling is dangerous! I'm going to stick around and make sure you don't do anything that reckless from now on!" you seriously doubt that she'll be able to interfere with you, but her clumsy cuteness might get you a discount somewhere.. You got Yuki-chan!
