With reference to your report More advantageous changes to the lotto game! (TMID, 22 May) lotto punters may wish to know that the chance of guessing correctly four numbers out of 90 on a lotto quaterno ticket is 1 in 511,038.

As far as I know, fewer than five players have guessed four numbers on the same ticket since the inception of the lotto game in 1922.
