Editor review

Waterfall Cipher is a substitution-cipher puzzle with forty hand-curated phrases. The format is the cryptogram puzzle digitised, and the discipline is what carries it.

What works is the propagation logic. Assigning one letter updates every instance of that letter across the phrase. Players build the decoding through inference rather than guessing.

Forty puzzles across three phrase-length tiers. Short phrases are warm-up; long phrases are weekend projects.

Tested over a month of Istanbul Marmaray commutes plus Istanbul weekend cafe sessions. Touch and keyboard input both work reliably.

Where the design earns its rating is the hint pricing. Hints cost score points; using them helps progression without negating skill.

Where I would push back is the absence of player-submitted phrases. The format would suit community content.

Four stars. Solid cipher puzzle with thoughtful hint economy. Recommended for word-puzzle fans.
