Tic tac showcases are very very long games: in fact we pay the registration once, we enter the queue, and must then validate, day after day, its position.
In this way, every day this validation is done, you gain a rank in the queue. If you do not do the validation once, you leave the queue and your registration is refunded!
So when you enter a queue and you see being the 365th in the queue, you will need a full year of validations every day to reach the first place. In reality, it will surely be less since it is very difficult to be so faithful (holidays, absences ...) and so many places are released as well.
