I think there are good points on either side on this one (LMI PPT vs Sudoku Mahabharat Pamphlet) so I think we should look at projector availability/cost analysis/etc. In fact, if we can show a PPT, the ideal thing to do would be to show a PPT about LMI and then direct participants to the pamphlets on the side for SM and SC (since I'm sure there'll be some U-18 participants or parents participating) so that something of focus is given while also showing there's more if they wish for it.

If I'm not wrong, we have already had an email space in the Times Sudoku rounds, and we have sent emails and smses to participants in the previous years without much response. This is why I feel a written pamphlet might go a longer way since these are mainly Sudoku fans coming from the written newspaper background, and probably rely on that more. Worth a try anyway :)
