Ice Cream Vendor

A counter, a queue and an order to get right. Each customer wants a specific cone, specific flavors in a specific order, and specific toppings, and the only difficulty is that they arrive faster than you can comfortably remember what the last one said. Ice Cream Vendor has no economy, no upgrades and nothing to unlock — it is a short-term memory test with a scoop in it, and the levels get harder by adding combinations rather than by speeding up a timer.
