Here's some things that all real Tamagotchi Connexions have.
-The package has the Bandai logo on it. IF IT DOES NOT, YOU ARE BUYING A FAKE!
-Version 1 package is blue, version 2 is orange (unless it's Twin Pack). IF THE COLOUR IS DIFFERENT, IT IS A FAKE!
-Version 1 has Mimitchi and the icons on the screen, Version 2 has Mametchi and the icons on the screen. IF THE CHARACTER IS DIFFERENT OR THERE IS SOMETHING DIFFERENT BEWARE!
-Fakes look kinda flimsy sometimes.
-If you can see what the back looks like, the back will have something to do with Bandai on the back though you can't read it all too well.
-If you see enough Tamagotchis you will remember all of their colours. There are simply too many to put down here.
-Real Tamagotchis in the store are always around $24.95 for version 1 and around $26.95 for version 2 (it's definitely that price in Australia). If it is around $10, it is a SCAM!
