Prisoners Chess Patch 1.10 Sandbox Mode!
Sandbox Mode is here!

Hey everyone,
Alot of our players were asking "what if?" What if my Knight had three perks before the first fight? What if I stacked every crit relic at once? What if the Inquisitor walked into Nightmare with a full back rank of Queens? So I built a place to find out.
What you can do in Sandbox
- Pick any hero and any Trial. No unlock grind in here.
- Set your starting Blood and Skulls. Be rich, be desperate, it's your call.
- Build your army: add extra units, give free levels and hand-pick perks for each piece type.
- Start with any relics you want. Yes, all of them if you like. I'm not going to stop you.
- Flip the Nightmare switches: Hell Fire, Devil Contract, Frail King and Nightmare Rules can each be turned on or off, on any Trial.
- Fixed or random seed. Replay the exact same map to test an idea, or roll the dice.
Share codes
Every setup turns into a short share code. Copy it, drop it in the discussions or send it to a friend, and they can paste it in and play your exact run. I really want to see the cursed builds you come up with, so please post them.
How to unlock it
Sandbox opens from the Home screen once any one hero has reached Nightmare. I wanted it to be a reward for people who already know how the game works and want to break it, not a way to skip learning Prisoners Chess :P
If something breaks, feels off, or you find a build that shouldn't exist, let me know in the discussions. I read all of it. Now go make something unholy.
