The 'Full version' of Quick Snooker is now purchased via PayPal, from within the game - You don't need a Paypal Account, you can pay with any debit or credit card, prices start from £5.
Please Install the free version of the game (if you haven't already) - then simply press the 'upgrade' button once you are signed in.
Buying before your trial expires actually makes sense - the balance of your trial is added to your membership/support period.
Don't be put off by the idea of membership - you buy most product features on a 'one off' basis and 'own' them.
Membership (for online play) and support is optional, but also great value, and we don't automatically renew anything.
