Toaru Majutsu to Kagaku no Puzzdex

Toaru Majutsu to Kagaku no Puzzdex (とある魔術と科学の謎解目録（パズデックス）), translated as A Certain Magical and Scientific Puzzdex is an action puzzle video game for iOS devices, Android devices, and mobile phones, featuring characters from both Toaru Majutsu no Index and Taru Kagaku no Railgun. It is planned to be release on February for Android devices and March for iOS devices.

Gameplay
The game uses chibi-fied version of the characters from the series. Teams of characters can apparently be formed and a copy of the character with a different color scheme can be found if the opponent already has that character in their team. Health bars appear at the top of each character during the battle. When the favoribiity of a character increases, it will be released to the "Utopia Stage" for playing by touching the screen as a special reward.

There are also events that allow the player to compete others as well as raid boss fighting with cooperation with other players. Sexy card illustrations drawn from the series will also be provided.

The gameplay looks similar to , where game is split-screen, with a role-playing game at the top where the player apparently gets to fight other chibi-fied characters from the series. The lower part of the screen is a puzzle game involving animals. There would also be character cards reminiscent of Toaru Majutsu no Index Struggle Battle.
