Don't you consider doing it the opposite way? Draw Metaspins first and then do the normal draw, of course including non-winner Metaspins entries. I mean obviously it will be a higher chance to win with Metaspins account anyway. But if you do it in this way the normal draw will be 5 less Metaspins already winner. Unfortunately I can't register for that casinoCorrect, however you cannot win both draws.
First, the normal draw will take place and after that the Metaspins draw will take place (with exclusion of any winners in the first draw)
