Café Server — free browser game

You're working as a barista in a café. A customer steps up to the counter, shows you their order for a few seconds, and then the order vanishes from the screen and you have to prepare it from memory. Click the drinks the customer asked for in the correct order using the drink buttons below — the sequence matters, and a single ordering mistake counts as fully wrong. If you click the wrong drink, you can undo your last pick with the Backspace key to correct it; press the 'Place Order' button to confirm your whole selection. With each successful order the next customer's request grows by one more drink; the first customer might ask for 2 drinks and the fifth for 6. You're allowed three mistakes in total, and once you hit the third your shift ends and the results screen appears; your score is the number of correct orders you fill during the game, and your best score is saved in the browser. Because this is a memory game, the strategy tips come from memory techniques: split the drinks into colour or icon groups (for example by temperature: coffee-tea-chocolate are hot; soft drink-soda-water are cold), repeat the order out loud as 'cappuccino-tea-water', or fix each drink's position in your mind for visual memory. Break long orders into 'chunks of three' (for example 7 drinks = 3+3+1) — this matches the natural capacity of human short-term memory and dramatically lowers your error rate. At advanced levels you'll get orders of 8+ drinks; at that point it's more effective to remember the order of drink groups rather than memorising each item directly.
