Every night at 11:35 Pacific, before the first draw, Sparky seals a BC Keno 10-spot for the next day and commits it to git. A random line is sealed beside it as the control. Both are played on paper, $1 on every draw, about 400 a day. Nothing is bought: you can't buy BC Keno from Alberta.
Virtual bankroll, $1 on every draw from the day you pick. Days before the first sealed night are a replay: the same frozen rule, run backwards. They show what would have happened, but nobody wrote them down in advance, so they never count on the scoreboard.
