Chief executive Dianne Thompson said Camelot was combating a "natural flattening" in sales with initiatives that included a raft of "good cause games" to raise £750m in support of London's bid to host the 2012 Olympic Games.
These include a "penny draw", welcomed by the National Federation of Retail Newsagents president Colin Finch as "exactly the kind of flexible thinking we need from Camelot".
A daily game will launch this autumn, with six draws a week and prizes from £5 to £60,000, subject to approval from the lottery regulator.
Lotto main draw tickets will be available online from this winter and on Sky Active from early next year. Adapted and bespoke games will be sold through these channels.
A European game, developed with France and Spain, is due to launch in early spring next year, if regulators give it the go-ahead.
Lotto will be available on mobile phones from summer next year, and new scratchcard games are being designed. A total of 28 scratchcards will launch in 2003.
