Missing this wonderful application – Trainyard Review

We still are keeping an ancient iPad to play this outstanding logic game! My kids and I love it, we each take turns solving a level (multi-solution) then compare the best approach. Extra points for elegant simple solutions, least track pieces, maximum clever reuse, and unique solutions. Hope the developer can find some time to update/recompile for iOS 11/12! At any rate, thanks much for making such a useful and enjoyable tool/toy!
