About this game

WALKING IN A WASTELAND WONDERLAND 🚧

That’s how the song goes, right? Well, now it does, seeing as how the apocalypse has come and gone and the last remaining survivors, yourself included, are left to rebuild society, starting with the local jail! Unexpected, yes, but just because the world got laid to waste doesn’t mean that all crime stopped. Craft, build, and defend your prison hub as you rehabilitate inmates while also building a shelter and trying to survive in this idle prison RPG.

THEY’RE IN THE JAILHOUSE NOW 🏚️

This game combines all the fun of idle games, where you’ll craft buildings, workbenches, and more that will collect resources for you in the background, with the fun of RPGs as you work to clean up the area, manage and expand the prison, and become an all-around jail tycoon. Along the way you’ll also have a chance to help rebuild your world, one reformed criminal and beautified spot at a time. Don’t go soft yet through: you’ve still got to defend your territory and survive!

We think you’ll love:

🛠️ Crafting: Simple items can turn into deadly tools and crazy weapons in your hands, all it takes is a bit of skill and a touch of forward thinking. Collect all manner of items as you clean up the last dregs of chaos, and then use these to help build new prison wings, weapons, and gear. Your survival depends on it!

⚙️ Upgrading: Once you have your base items, don’t sit back on your laurels! Upgrade them to the max so no matter what the wasteland throws at your shelter you’ll be prepared. In addition to weapons and gear you’ll also need to ensure your survival by constructing buildings and then setting up defenses and protecting them. Who knows what’s out there!

🏔️ Exploring: As your need for resources grows, you’ll have to travel further and further afield to collect items to keep your prison running and ensure your survival. Enjoy the opportunity to see a whole new world post-apocalypse and explore all manner of mysterious places as you roam. Don’t be afraid of a little danger though, that’s usually where you’ll find the best loot stashed.

👨‍🏭 Growing: Grow your jail, your world, and even your character! The more you progress, the more skills will be unlocked, thus boosting your little guy and helping you survive.

🎮 Playing: Your survival might be on the line, but this is still a game! You can enjoy this idle wasteland exploration game anytime, anywhere, as no internet connection is required. Squeeze in a little world building and jail building no matter what the situation.

SURVIVAL OF THE SMARTEST 🧠

Test your post-apocalypse survival skills now in this fun and exciting idle game, where as one of the last survivors you’ll need to build a prison to rehabilitate the bad guys, maintain it, and make the world a little better in the process.

i really enjoyed this game, but ads are the biggest issue. so I paid to get rid of ads, so I thought. after sending 8.99 to remove ads, then paid another 7.99 for the 3 x hammer. I thought this was it. how wrong was I... at level 7, you don't have enough resources in one hit, for example 1 battery requires 10 oil drums, which takes 45 seconds to create 1 drum, so when you start to upgrade the cleaner requires 30 oil drums which is about 25 minutes play. you want for anything else apart from wait

I like the game okay except that I wish that it allowed for more gamer autonomy. If the gamer was allowed to upgrade things like the laundry worker or the hammer as you are able to obtain the materials rather than being led by the nose by the computer one by one task at a time it would be more fun. Just limit when things become available to be upgraded by player level.

I WAS enjoying this game. it hasn't opened in 4 days now. It gets stuck on the opening "loading" and no longer progressed past that. I left it for over 30 minutes and it never progressed past the opening app loading. Disappointing. waste of time if its just going to glitch when you play enough to start building up supplies and open areas. and then they tell me to reach out in the in app support....uummm hello!! the app doesn't open so how is one to do that exactly? I deleted the app after 6 days
