If you have ever played any of Nintendo's Picross games, you will feel right at home.

The goal is to reveal the hidden picture in the grid by filling in the correct tiles. The numbers help you figure out which tiles need to be filled in.

The game has 210 puzzles + 7 bonus puzzles unlocked with the e-reader. The puzzles are divided into 11 "packs", and each pack has a theme:

• Entomology
• Art Museum
• Fantasy
• Zoology
• The Nineties
• DIY
• Classroom
• Taiyaki Fabulous part 1
• Taiyaki Fabulous part 2
• The e-Reader
• And a surprise pack

Each theme has a unique setting, for example here is what a The Nineties puzzle looks like.

Prefer the Mac? We got you.

And here is a Fantasy puzzle.

Two of the puzzle packs celebrate the game Taiyaki Fabulous. A very cool adventure nonogram game for the original Game Boy. The creator of Taiyaki Fabulous is also working on Pixel Pup.

Two player mode is done using the GBA link cable. There are two ways to play:

• Cooperatively: work together on the same puzzle to solve it faster.
• Competitively: who can finish the puzzle first?

Pixel Pup was also going to be released as an e-Reader game. That has hit some manufacturing snags and is on indefinite hold. For more details, check the announcement.

As a consolation, you can use your e-Reader to scan in Series One cards to unlock bonus puzzles. More info here.
