The Switched Lunch

The setup fits in two lines. Three friends order a falafel wrap, a tomato pasta and a garden salad from a café, and nobody gets the one they ordered. Your job is to rebuild who took which bag.

Four clues, opened one at a time, give you just enough to pin it down. One of them settles a single bag straight away, and from there it's a couple of minutes of elimination. It's a gentle puzzle, more warm-up than brain-burner, which fits the stated age of 10 and up and a spare five minutes.

You match lunches to bags by dragging, tapping, or using Tab and Enter, so it works on a phone, a laptop or with a keyboard alone. A hint button gives up to three nudges, and once every bag is right the page explains why. Progress saves in the browser, there's a reset if you want a clean start, and nothing asks you to sign up.

This is the first of five cases in Five Small Mysteries, which At Yours sells for US$3.99 as a single payment with 365 days of online play and no auto-renewal. The paid set includes this case, so buying it adds four new ones, each estimated at 5 to 10 minutes. The other cases use the same format of four observations, one question, progressive hints and an explained solution, so this free one is a fair sample of the set. At Yours also offers a Plus subscription at US$4.99 a month or US$29 a year across its wider catalog of family and party games.
