Compare Below the Surface: Assassin's Prison prices across trusted key stores and find the best deal. Developed by QZQ Studio, KKK. Published by QZQ Studio. Released on 5/19/2023. Available on PC. Genres: Adventure, Indie.

A two-hour detective puzzler where the deduction board actually thinks with you, if you can forgive the rough translation and thin production polish.

The deduction board is the real thing here, and that alone justifies the runtime. Most small detective games hand you evidence and call the finding of it the puzzle. This one makes you link testimony to object to contradiction on a corkboard that refuses wrong connections without telling you why, so the reasoning has to happen in your head rather than in a checklist. Crime scenes are point-and-click, deliberately still, and the pacing trusts you to sit with a room longer than the genre usually allows. The cracks show fast. Text is stiff in places, art assets vary in confidence from scene to scene, and a couple of logical leaps land more on intuition than deduction. Six user reviews is not a community, it is a handful of people who found something and said so. But this is a two-person team shipping a genuinely clever mechanic and then stopping when the story was done, which is a discipline bigger studios never learn. Come for the board, forgive the edges, leave before it overstays. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
