How do I track levels for level Select?

I have a game with 12 levels and a level select screen. At first all levels are locked except the first. If they beat the first they unlock the second and so on. To beat the level the player has to get to a flag at the end. All the levels are in separate layouts, but share a single event sheet. I can't think of a good way to track which levels they have unlocked. Any ideas?

..something like this?

Hi,

I've made a level chooser template that is perfect for multilevel mobile games. The user can use swipe to browse between and select levels. You can check it out here: https://www.scirra.com/store/royalty-fr ... ector-1006

It has a simple unlock method that takes the layout name as param, that I think would suite your needs. Check out the videos from the link above and try the demo to see if it is interesting. Good luck with your project!
