A number logic puzzle for iPhone
Put 1 to 9 in the circles so every equation is true. If you like Sudoku, you'll learn it in a minute. Then each tier adds a new move.

Try it. Tap a digit to fill the ringed circle. Arrows point to each line's answer.

Play
The digits and the goal stay the same. What you need to reach it grows. When × and ÷ first appear, the board tells you how they read. These are real puzzles from the game: pick one and play it here.
Unlocks
Each zone is a transit map, and each puzzle is a station that lights up when you solve it. Solve along a line and the next one opens where they meet. Finish a zone for its badge, and some zones earn a new theme.
Zone 2 · Tangle
Tap a ringed station to solve it.
Your formula: puzzles solved on each line, Easy to Expert. Every zone adds to the one on your home screen.
Drag the map sideways to see all of it.
