In order to view the video tutorials and other associated resources, you must have an active Full Membership. Full Membership costs either £10 for 1 month or £25 for 12 months access to everything within the members area of numberstacks.co.uk. This is a one off purchase price with no ongoing commitment. When your membership expires, it will switch to a Basic Level (which still gives you access to all the games) and you can then decide whether or not to purchase an additional Membership period.
Full Membership can be purchased online via our Buy & Subscribe page in the main menu.
Schools: School memberships are available for schools requiring multiple users. Please contact us directly for an individual quote and to arrange payment via invoice.
NB. If a single membership is used on multiple devices, this will result in the membership being temporarily suspended until the account is unlocked.
