The Babel Cipher

What it is

The Babel Cipher is an offline word-building puzzle where words are movement rather than score. You hold a rack of eight letters over a procedurally generated grid, and the word you spell decides how far your tiles travel, so reaching the exit means burning a path towards it one word at a time.

Each word must begin with the last letter of the one before it. Play a long word without looking ahead and you can end up stranded on a letter almost nothing starts with, and breaking the chain more often than your difficulty allows ends the run.

How it plays

Three difficulty levels each carry their own allowance for broken chains, and an endless scored mode keeps local high scores. A reshuffle costs you a few points when the rack refuses to cooperate, and a short tutorial runs before your first game, skippable afterwards.

The game needs no connection, no account and no payment after the download, and keeps your settings and high scores on the device.

Where the mechanic came from

The idea that word length should be distance rather than score came from my final-year project at Brunel, Deus Ex Machina, a serious game for adults over sixty at risk of mild cognitive impairment. The premise was that vocabulary retrieval, pattern recognition and route planning could be exercised in one decision if spelling a word was also the act of moving.

This game takes that mechanic out of the clinical frame and borrows the world rather than the study. In the fiction of Aetheria, the Babel Cipher is the pattern that has scrambled the Aetheric communication networks for fifteen years, shifting daily, named by the linguists who failed to break it after the tower where a shared language was lost, though the narrative itself stays with the parent project.
