Just HalfHow to play & tips

What kind of game is it?

Cake, rice balls, taiyaki and more—24 kinds of food appear across 24 stages, one per stage. You clear each stage by how close the two pieces come to 50 : 50.

How to play

Choose a stage on the home screen, tap the button to play it, and slide your finger across the cutting board. The line you trace keeps going straight and cuts the food from edge to edge.

Each attempt gives you 3 cuts. Cut closer than the stage's goal within those 3 to clear it. The goal gets stricter every 4 stages (from under 4% to under 0.7%). If none of the 3 reach it, just try again. Lines that miss the food or are too short don't count. In Practice, you can choose a food and cut the same one as many times as you like.

After cutting, tilt your phone to turn the pieces and see the cross-section better (turn it on with the button at the top right of the play screen).

Ratings

Your rating depends on how far you are from 50% (the error): under 0.1% is “Divine blade”, under 0.5% “Master's hand”, under 1.5% “Nicely done”, under 4% “So close”, and anything more is “Rough cut”.

Stars and sharing

Clearing a stage earns stars: 1 for clearing, 2 for being off by less than 1.5%, and 3 for less than 0.5%. You can replay cleared stages as often as you like to earn more stars. The home screen shows your total stars out of 72.

When you clear a stage, tap Share to post your result with a picture of the cut board.

Tips to get better

• The line runs all the way to the edge, so its direction matters more than its length. The two points where your swipe starts and ends set the direction.
• For round foods, any line through the center gives almost exactly half. But when a slice is missing, shift the line away from the missing part to make up for it.
• For lopsided foods, shift the line slightly toward the thick or heavy-looking part.
• The dotted line shown after cutting is where the same direction would give exactly half. Aim closer to it next time. Cutting the same food again and again in “Practice” helps you learn its shape.

Notes from the creator

I wanted to capture the joy of slicing food neatly, in stages that get a little harder each time. The cut food turns 3D so you can see the cross-section.
