Delta0

Delta0 is a puzzle game where you arrange numbers in circles to match the sums shown at the corners. You can drag and drop circles between positions, and complete a level by reaching a Delta0 at all four corners: each triangle’s sum must match the expected value.

Solve the puzzles

Each triangle connects three large circles and represents their sum. A green triangle indicates that the sum matches the expected number; three small circles appear when it is correct. A red triangle indicates a mismatch, with a number showing the difference between your sum and the expected value. For example, 1 + 1 + 1 matches 3, while 1 + 0 + 1 falls short by 1 and 1 + 2 + 1 exceeds it by 1.

The game has 1,500 static levels: 500 Easy, 500 Medium and 500 Hard. It also includes eight modes: the three static difficulties, plus the infinite-level modes Daily, Quick, Timer, News and Messages/Emails.
