Instant ticket game prize structures vary from game to game. The detailed breakdown of numbers of prizes in each category is, for business reasons, not released but for each individual game the prize structure, approved by the Minister for Finance, is formally certified by Accountants Ernst & Young.
The national lottery publishes average odds of winning prizes on all instant game tickets. For example, Allcash offers odds of 1 in 6.6 and "Winning Streak" 6 offers better than 1 in 9 of winning a cash prize. In order to realise these odds of winning the majority of prizes are in the lower prize categories.
