Spellcase

Spellcase calls itself a daily puzzle of spelling and deduction, dressed as a detective case. Each numbered case breaks eight words into letters and scatters them across an 8x8 grid, 64 letters in all, with no loose ends: every letter is used once. Case No. 1 ran on 1 September 2026, and a new one opens each day.

A case starts with the bare grid. Tap to reveal the eight starting letters, then open the case file: a list of eight clues with the length of each answer, written in a playful, punning style (on 18 October they included Big leafy flowering pH meters, 9 letters, and Child in the "why" phase, 11). Pick a clue, work out the word, and spell it by tapping its letters in the grid. As words come out the grid thins, and the letters left over narrow down the harder clues, which is where the deduction comes in.

When you are stuck there is help, at a cost to your grade: reveal another clue for a word, reveal the vowels, reveal the next letter, or sweep the grid down to a few tiles. A finished case is graded on letters shown and misspellings, and the result can be shared as a short report.

Solved cases go into a casebook. Missed days can be unlocked from the archive and played later, cold cases add extra puzzles beyond the daily, and Build a Case lets you put your own words into a case and send its link to someone else. The game runs free in the browser with no account and no ads, laid out as a phone-width column on a desktop too. It suits players who like crossword-style clues but want a puzzle that also rewards working from the leftover letters.
