Case Open is an addictive puzzle game from 2020, designed to play in waiting rooms and other places, without any time stress or 'out of lives' messages or having to spend money on power-ups. The game is completely free with no advertisements, no banners, nothing. Goal: Guide Casey to the exit by collecting all required coins. There are 400+ lessons that will prepare our Hero for life in the field as a full fledged spy. - The App itself has an extensive Help section, explaining all items. - Look at the screenshots to see some items like door, transporter, etc - Difficult levels have a walkthrough video, accessible from within the app (pause screen). - If you register you get 5 skip options which allows you to skip 5 levels of your choice, when you solve a previously skipped level, you regain the skip. - When you have finished, you are ready to take on real Spy missions in Case Closed, another puzzle game. It's available for free from your favorite App store. We hope you enjoy the game. Jake Solutions
