The gambling store version of keno has a high house edge of ~30%, but still with low risk keno tickets those playing smart would have a 60% chance of getting back all the promo money as a withdrawable balance or even winning more. Upon noticing this I told my friends and family to also create accounts and many of them got more out even than the promo balance.
Most of my family have never gambled but free money is too good to skip in any case. So we're now all waiting for the next promo, if there will ever be any.
I'll never skip that free money either, it's a loophole that the management overlooked or they deliberately do that to give away that money, if they do not know this, I'm sure they are aware of this now and will fix it the next time they launch a promo,
I haven't, but if there's a chance I'll take it and I will from now on look for loopholes maybe there will be promotions with similar loopholes that you exploit, but if it's online I will report it as a bug in exchange for small cash.
