Runescape 3 has promotions that can be completed in a set amount of time for a reward either cosmetic or currency/xp
Every row or column you beat gave you a reward for completing it, allowing you to prestige it up to 5 times and beating them again
It ranged from easy to difficult tasks and I think it worked something like this but rather than in a sequential order you could beat them as you wanted
