Case contract

Point-spread teaser. legs rows are [team spread line, team margin of victory]; every line is moved in the bettor's favour by points (adjusted = line + points). A leg wins if margin + adjusted > 0, pushes if = 0, loses if < 0. Any losing leg loses the ticket. Pushed legs are dropped; fewer than 2 remaining winners refunds the stake. Payout by winning legs from the American table {2: -120, 3: +160, 4: +260, 5: +400} (5 or more pay +400). Return [status, return cents rounded down].

Why this case matters
