A first-person puzzle platformer where you conjure triangular surfaces to walk on walls, redirect light beams, and rethink gravity in increasingly brain-bending tower levels.

TRI: Of Friendship and Madness is a first-person puzzle platformer from Rat King Entertainment that hands you one deceptively simple tool - the ability to summon flat triangles in 3D space - and then spends its entire runtime finding new ways to make that tool feel both indispensable and deeply weird. You are working through a series of towers and dungeon-like chambers, climbing surfaces that have no business being climbable, and bending light rays off your placed triangles to hit distant targets. It sounds abstract on paper, but in practice the mechanic clicks surprisingly fast, which makes the moments when the game flips your orientation upside down land with a satisfying gut-drop. The puzzle design is where TRI earns its Very Positive reputation. Each chamber introduces a new wrinkle on the triangle mechanic - sometimes you need to create a ramp to reach a ledge, sometimes you need to angle a reflection just right, and sometimes you realize mid-solve that you have been thinking about the geometry entirely wrong. The difficulty curve is generous early on and then takes a confident step upward without ever feeling punishing. There is no combat, no fail state that throws you back far, just a quiet invitation to think differently about three-dimensional space. Players who enjoy games like Antichamber or early Portal-era spatial puzzles will recognize that particular flavor of eureka moment. The art direction leans into a stylized, somewhat austere look - lots of geometric architecture and muted tones punctuated by the vivid glow of light beams. It is not technically impressive by any modern standard, but it suits the contemplative mood well. The audio is similarly low-key, ambient enough to keep you in the zone without becoming wallpaper. The story framing, hinted at in the title, is present but thin - do not come here expecting rich narrative payoff. This is a mechanics-first experience dressed in light lore. Where TRI stumbles is in its camera and movement, which can feel slightly imprecise when you are placing triangles at awkward angles near geometry edges. A few puzzles tip from satisfying difficulty into mild frustration not because the solution is elegant but because landing a triangle exactly where you need it requires fiddlier input than it should. The game is also short - a focused player will finish in four to six hours - which is worth knowing before you commit. For what it is, though, TRI does one thing exceptionally well: it makes you feel spatially clever. If you like puzzle games that respect your intelligence, do not overstay their welcome, and build their entire experience around a single mechanic with genuine depth, this is a well-crafted small package. Just go in knowing it is a puzzle game first, a platformer second, and a narrative experience a distant third. Alex, 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.
