Goal: pick a sandwich in the kitchen, then collect one of each ingredient on its recipe (the checklist at the top right). Drag the cannon barrel to aim, drag the tower's plate to change the distance (the sliders fine-tune both), then press Launch.
- Force pushes the fork along a barrel of length
s = 2 m. Mass is m = 2 kg, so a = F ÷ m and v = √(2·a·s).
- Sideways the fork moves at a steady speed:
x = v·cos θ · t. Up and down gravity pulls it: y = v·sin θ · t − ½·g·t², with g = 9.8 m/s².
- Force, acceleration and velocity are linked. Change one and the other two follow.
- Hit a fresh layer of an ingredient you still need: +100 points and +2 seconds. It flies to your plate on the right.
- Hitting an ingredient you already have, or one that is not in the recipe, costs a life. So does a miss.
- Complete the sandwich for a finish bonus: points for every second and every life you have left.
- Three right layers in a row: +30 bonus on each one after that. Three wrong layers knock the tower over.
- The stack never ends: a new random layer drops in after every hit. Medium and Hard add decoys from other recipes.
- Hard mode: some layers are rotten (green spots and buzzing flies). Hit one and you lose ALL your lives at once.
- Quiz: after every round Sandy asks questions about your own shots. You can skip a question and look at it in the summary afterwards. Right answers earn quiz points, and more points unlock new sandwiches, from the simplest to the best.
- Profile: pick a hat, hair, outfit, skin tone and accessory for the character next to the cannon. The Tutorial button on the title screen teaches the basics in a safe sandbox.
- Hide the arrow: no marker shows where the ticket's ingredient is. Those scores get a no-hint badge.
