Tekuteku Pikmin (literally Marching Pikmin) is an e-Reader application from the Pikmin Puzzle Cards-e series, requiring an e-Reader, Game Boy Advance, Nintendo GameCube Game Boy Advance Cable, and a Japanese Nintendo GameCube with Pikmin 2.
It is a grid-based puzzle game, where the player must control several Pikmin to reach treasure. Since all Pikmin move at once, strategy is required to get all the Pikmin to the treasure.
A cancelled remake of Manhole meant to be released for the e-Reader. It was represented by a white Luigi on the package of the cancelled Game & Watch-e Collection. It was one of the games in the Collector Version.
Mario vs. Donkey Kong Card e+ is an e-Reader Cards set released in 2004. There were five cards released, and they were only given to 1,000 people who competed in a competition in Japan. The game was not made available in America. Each card, when scanned, would give the player an extra level in the Game Boy Advance video game Mario vs. Donkey Kong. While there were 12 spaces available, Nintendo only released five levels. A sixth card (actually the first to be released) wasn't available in this set.
Hamtaro-e is an e-Reader video game released in 2003, exclusively in Japan. Not much is known about the game, though it's possible that it gives the player extra features in the Game Boy Advance Hamtaro games (much like Super Mario Advance 4: Super Mario Bros. 3-e and Animal Crossing-e).
Pokémon Battle-e were e-Reader card sets that was made to be used with Pokémon Ruby and Sapphire, and later Pokémon Colosseum, Pokémon FireRed and LeafGreen, and Pokémon Emerald. The later sets were not released in America. When connected with the game, the player could receive extras such as new berries, and new trainers to battle.
Oddly, the Pokémon you battled through the trainer cards would not give your Pokémon any experience points or items after they were completed. When the player scans a berry card, you'll receive a berry from a character.
