What should I do next?

At the GPTreaure Lotto Offer I downloaded and installed that BoontyBox Play Toad , Real Arcade etc. I downloaded and intstalled a random game then what? I'm not sure what to do next and I'm lost am I already in the lotto is there still something else?

i guess you play the game once then you mark the offer complete.

if you dont know how to mark offers complete you go to
my offers
then you scroll down to the dropdown box and submit the one you completed.
if you havent chosen a payment type , do so

And please remember once you submit the ticket it's a draw (Spanish: Sorteo) so not everybody wins.

Goodluck everyone :-)
