I presume that this 50% bonus game tickets is good for only the very next purchase of game tickets?

Thanks!

Yeah it says it's only valid for the first purchase during the campaign period.

If you're a new user, you already get this bonus. So you would then be able to get this charge bonus after signing up. (So they don't like cancel the other out)
