Listen to the cry of the day and name the Pokémon. You can replay the audio as many times as you want before answering.
Length and pitch direction separate families better than timbre does, and evolutions tend to share the sound of their base form.
How to play
Cry mode plays a Pokémon's cry and asks you to name it. You can replay the clip as many times as you want before answering, and there is no timer — the difficulty is entirely in the listening.
It is the hardest mode on the site, and it stays hard even for people who clear the others quickly. Early-generation cries are short bursts of synthesised noise built from a handful of waveforms, and a lot of them genuinely do sound alike.
Two traits separate cries better than anything else: how long the clip runs, and whether the pitch rises, falls, or holds flat. Fix those two before you try to name anything, because together they already split the field into rough families.
Texture is the third axis. A cry is either fairly clean and tonal or mostly noise, and that difference tends to track what the Pokémon is — tonal for birds and small creatures, noisy for heavy or armoured ones.
The first generations of cries were generated on very limited sound hardware, with a small set of parameters shared across the whole roster. Many species were built from the same base waveform with the pitch and length tweaked, which is exactly why several of them are near-indistinguishable by ear.
Later generations have longer, more detailed cries with far more distinguishing character, so the mode gets noticeably easier when a newer Pokémon comes up. That unevenness is a property of the source material, not of the puzzle.
As often as you like, before and between guesses.
Only for the sound modes. Every other mode is fully playable in silence.
