Monorail

November 14, 2017

This app has been updated by Apple to display the Apple Watch app icon. FINALLY -- an update so Monorail will run in iOS11 [We heard your pleas and thank you for your past support] EVERYTHING IS NOW FREE (AND WITH NO ADS) All 3 puzzle packs (total of 880 puzzles) now completely free and unlocked! This was the easiest way to do a quick update, and to make sure that previous paid users can still access all their puzzles. Thank you everybody for your past support. BUG FIX The nasty "CLEAR button" crash is now fixed. IMPROVEMENTS More reliable tapping on puzzle rails and scrolling menus.
