There aren’t many puzzle games that can claim to have a 13th-century origin story, but Cipher Monk: Cassette Equation has one.

The latest entry in Afil Games and Heavy Sheep’s curious puzzle series has arrived on Xbox One, Xbox Series X|S and Windows PC for £4.19, once again asking players to get their heads around the numerical system used by Cistercian monks.

Following on from Cipher Monk and Cipher Monk: Ancient Calculus, Cassette Equation takes the series in another mathematical direction. This time, however, it seems as if the emphasis is less on mental arithmetic and more on observation, positioning and figuring out how those rather unusual numbers fit together. But what do we know? We’ll find out in review soon.

At A Glance

  • Game: Cipher Monk: Cassette Equation
  • Formats: Xbox One, Xbox Series X|S, Windows PC
  • Price: £4.19
  • Publisher: Afil Games
  • Developer: Heavy Sheep
  • Genre: Puzzle

A Medieval Number System Makes A Return

The basic idea is simple. Ish. You’re presented with pieces representing the ancient number system and need to arrange them to create the number required by each puzzle.

Doing so involves dragging, rotating and positioning the pieces until everything lines up correctly. That makes Cassette Equation a game of logic rather than speed, with the satisfaction coming from spotting the right combination rather than rushing towards the answer. There are 35 levels to work through, and the presentation is deliberately uncomplicated.

Learning As You Go

That learning element has always been an interesting part of the Cipher Monk concept. The first game introduced players to its unusual approach, while Cipher Monk: Ancient Calculus took things into considerably more mathematical territory.

Our review of the original Cipher Monk awarded it 3/5, praising its different approach and accessible puzzle format, although we felt it needed to do more to explain its mechanics early on and provide enough content once everything clicked.

Ancient Calculus also received 3/5. As we put it at the time, it was a game that could make you feel like “a moron” if maths isn’t exactly your strong point.

35 Puzzles To Decode

Cassette Equation appears to be following on. The further you progress, the more comfortable you should become with the symbols and the different ways the pieces can be combined. It’s the sort of puzzle design that should reward patience rather than brute force, with each solved level helping to make the next one a little less mysterious.

For £4.19, Cipher Monk: Cassette Equation offers another compact mathematical diversion for Xbox and PC players. Whether you’re already familiar with the series or this is your first encounter with the monks’ peculiar numerical language, there are 35 puzzles waiting to see whether you can crack the code.

You’ll find Cipher Monk: Cassette Equation on the Xbox Store. There are three versions to consider, so take your pick from the optimised for Xbox Series X|S version, one that plays on Xbox One, or a Windows PC drop. If you really like what you find and fancy a big old bunch of Gamerscore dropped onto your account, purchase all three!
