Hashi is a number puzzle that also goes by the name of Bridges, Chopsticks or Ai-Ki-Ai in Europe. It originated in Japan under the name Hashiwokakero.

It is an exciting puzzle game, which doesn’t require math skills, it involves connecting “islands” of different numbers to one another, either by a single or double bridge, until each island has the correct number of bridges.

Hashi is extremely easy to learn, and fun to play. It’s faster paced than Sudoku, and helps develop logical deduction skills and reasoning. Great for kids and adults.

Quick instructions are below, full tutorial is in the app:

Press IN BETWEEN numbers to create bridges.
Simple TOUCH interface. No swiping or double clicks.
Press ONCE for a single bridge.
Press TWICE for a double.

Good luck!
