Brain Puzzle 3 Level 20

Overview

Level 20 says "Help the barista make 10 different coffees." A cafe counter is lined with about nine identical cups of plain black coffee, while a tired blonde customer slumps at the end and the bottom line welcomes "Welcome in!" The barista in a yellow-red uniform stands behind the counter. Around the back bar are the ingredients: a cocoa jar on the pink fridge, a coffee-bean bag, a bottle of whiskey, a bag of "Uncle Tom's Matcha" powder, a water dispenser, a coffee machine, and a chalkboard menu. The job is to turn the identical black cups into ten different coffee drinks.

• Difficulty: Easy
• Estimated moves: 8

Step-by-Step Solution

1. Look at the problem. Every cup on the counter is the same plain black coffee. The customer wants variety, so each cup must be customised with a different ingredient combination.

1. Tap the cocoa jar. Add cocoa to a black cup to make a mocha. The barista is shown holding the jar, and the hint "Here's your custom latte" appears as the first custom drink goes out.

1. Tap the matcha powder. Add matcha to another cup to make a green matcha latte.

1. Tap the whiskey bottle. Add a splash to a cup to make an Irish-style coffee.

1. Open the pink fridge and use the milk. Pour milk into cups to make plain lattes/caffè lattes; the fridge is shown opened and emptied as the milk goes out.

1. Tap the coffee-bean bag / machine. Pull extra espresso shots to vary strength, and use the water to adjust each drink.

1. Keep varying until the cups run out. With each customisation, one cup leaves the counter. The cup count visibly drops from about nine to five (frame 33) to three (frame 66) as the drinks are served. The hint "One special coffee, please" marks the last few.

1. Finish the order. Once every black cup has been turned into a distinct drink and served, the counter is empty and the pink fridge stands open; the red "Completed" ribbon appears.

Strategy & Reasoning

This is a combinatory cooking puzzle: the base is identical black coffee, and the on-screen flavourings are what create "ten different coffees." The game signals progress purely by the shrinking number of cups on the counter and the running drink names ("custom latte," "one special coffee"). There is no hidden recipe to guess — you simply assign each visible ingredient to a different cup until the lineup is served.

The props map one-to-one onto classic coffee variants: cocoa = mocha, matcha = matcha latte, whiskey = Irish coffee, milk = latte, beans/machine = espresso strength. The chalkboard menu, the cow painting, the cat, and the window are dressing. The efficient approach is to tap each ingredient once per cup, working through the lineup, rather than repeating the same addition.

The only thing that matters is cup count: keep customising until the counter is clear. The timer just pressures speed, not correctness.

Tips & Common Mistakes

• Mistake: adding the same ingredient to every cup. They must be different coffees; use cocoa on one, matcha on another, whiskey on another, milk on others. Variety, not repetition.
• Mistake: forgetting the fridge milk. Several drinks are lattes; open the pink fridge and pour the milk out, or those cups stay plain black.
• Mistake: stopping while cups remain on the counter. Watch the cup count — the level only completes when every cup has been customised and served.
