How do I subtly flirt with a guy on an app?

[Colm9000]

I would start of with a compliment.
Us guys really love compliments since we rarely get them.
Trust me it's a easy way to start flirting, don't over do it though as he could lose interest in your compliments

Good call. He'd figure you out and be bored in no time.

Send him a pic of u and tell him playing with this can be it new hobby😛

Id go with not being subtle and not play games

Flirt like you would flirt here
