NLCB is a free iPhone app developed by Computers Controls Ltd. It allows users to access the official results of major National Lotteries Control Board (NLCB) lottery game draws. The app also includes a number generator to help users decide which numbers to pick. Additionally, the app features a "Read the Signs" section that provides insight into the most frequently appearing Play Whe marks by checking news feeds from across the country and the world.

With NLCB, users can find NLCB stores based on their current location or browse all available store locations. It is important to note that the numbers generated in the app and the popular marks mentioned in the "Read the Signs" section are not intended to be actual suggestions for winning draws. Users are solely responsible for the numbers they play when purchasing lottery and related game tickets.

The NLCB Offices are located at #Duke Street, Port of Spain (Tel: , Fax: ), #73 Mucurapo St., San Fernando (Tel: ), and TIDCO Mall Sangster's Hill, Tobago (Tel: ).
