Simplex (The Irish Times)

About Simplex (The Irish Times)

Simplex is one of the puzzles on The Irish Times crosswords page, next to Crosaire, Sudoku, The Daily Eight and the News Quiz. Each puzzle is dated (the latest on the page was Saturday, 3 October 2026), and an Archive link opens earlier ones.

It is the paper's straight crossword: every clue is a simple definition or synonym, so you need vocabulary rather than knowledge of cryptic conventions. It uses the same grid as that day's Crosaire, which makes it a common stepping stone for solvers who later want to try the cryptic.

The puzzle runs in the PuzzleMe player from Amuse Labs, in the browser or in The Irish Times app, with the usual check and reveal options. Like the other Irish Times puzzles, it is part of a digital subscription.

Tips

• Fill in the short answers first; they give letters for the longer ones.
• Once Simplex is done, try Crosaire on the same grid to learn how cryptic clues work.
