GeoLotto (previously known as GeoSweep) was a privately owned, online, map-based lottery game operating in the United Kingdom.
[3][4] In 2013 it was revealed that the Atlantic Lottery Corporation spent nearly C$2 million promoting Geosweep before cancelling the game.
Each square had an equal probability chance to win one of the various prizes assigned randomly at the end of the game.
[9] Players could enter by paying for a square for a fixed number of weeks or they could subscribe for ongoing entry until they decide to cancel.
GeoLotto was regulated by the UK Gambling Commission, certified by GamCare and carried the 'Verified by Norton' tag.
