The service
Zovo Cross Sum Puzzles is a tool provided by Zovo, a brand operated by autom8 LLC for use inside ChatGPT, Claude, and other MCP clients. Zovo Cross Sum Puzzles makes printable cross-sum puzzles for puzzle fans, teachers and students. Each grid from 6 x 6 to 12 x 12 has white squares to fill with the digits 1 to 9 and dark clue squares with sums: each run of white squares across or down adds up to its clue, and no digit repeats in a run. Choose the size and difficulty (easy, medium or hard). A solver checks that each puzzle has one solution before the PDF is made. The PDF has 1, 2 or 4 puzzles per page on Letter or A4 with a title, a name line and answer pages. The chat card lets you solve a puzzle on screen and check your entries. The same seed reprints the same puzzle.
