Welcome to the iPhilter arcade. Every game here teaches your water while you play it — no lectures, just contaminants, filters, and the occasional glass of something you would not want to drink. New games join the bench over time.

Don't Fill the Glass — Water Hangman

A contaminant is hiding in the word below. Guess its name letter by letter. Every wrong guess pours more murky water into the glass — eleven wrong guesses and the glass is full. Guess the word first and the water stays clean.

Hint:

The glass is empty. Clean start.
