Nintendo has announced that pre-registration has now opened for Super Mario Run on Android smartphones and tablets and you can sign up here to be ready to play. Hopefully the game will have a better sale rate on Android than it did on iOS where actual purchases were low. See the announcement below
Attn @Android users: Pre-Register now to be notified when the official #SuperMarioRun is available on @GooglePlay https://t.co/rYJAIDUdO5
