Snowflake is the one Psi card that does not follow the standard psi game template.

Standard template: "If you and the runner spent a different number of credits, do X."

Snowflake template: "Do X if you and the runner spent a different number of credits."

I guess you could say it's a special... —
I appreciate this. —
Aiki is similarly weird. My interpretation of the Corp 'winning' a psi game was if you spent a different number of creds to the runner (i.e. The runner could not guess correctly). With Aiki, you have to basically lose the psi game to prevent the runner to draw cards: You and the Runner secretly spend 0, 1, or 2. Reveal spent credits. If you and the Runner spent a different number of credits, the Runner draws 2 cards. —
