The shop
You keep the shop. Each customer writes rules for an outfit. The photographs show the cap, hoodie, tee, jogging bottoms, jeans and leather jacket that are in stock. Choose one answer and present it. Three of the four answers are wrong.
Logic
A typical list asks for a cap, a hoodie and trousers, with all three colours different. Trousers means jeans or jogging bottoms when the list says so. An outfit is wrong if two pieces share a colour, if a garment is not on the list, or if a banned colour is used.
The maths
- If repeats are allowed, multiply the choices. Two hoodie colours and three jean colours make 2 × 3 = 6 outfits. Adding those numbers is a wrong answer.
- If the colours must all be different, the later pieces have fewer colours left. Three colours give 3 × 2 × 1 = 6 outfits. 3 × 3 × 3 = 27 counts colour clashes as well, so it is wrong.
- Two kinds of trousers, or a hoodie or a leather jacket, means you multiply again.
- A fraction or a probability has to be in its lowest terms. 2/6 is the right count, but the answer is 1/3.
- For a budget, add the prices. A colour rule can still rule out an outfit you can afford.
The shift
Six customers. Win the shift with at least five right answers. The bar is the customer's patience. A quicker right answer scores more, and a run of them builds a combo. Easy, Classic and Hard all use choices that can be wrong. The daily shift is the same Classic shop for everyone until midnight UK. Signed-in scores count towards badges and the daily league.
