The Game will be a location based group / versus game.
Players will be able to download the app for free and then pay per game.
The games can be played alone, in a group or in vs mode (only one player pays and invites other players to join him. max 5 in the same group, max 6 in versus mode with two groups of three or three groups of two).
The game will be city based (Zürich initilaly). In the city of Zurich there will be some 100 check points (this needs ability to administrate via DB) that players will need to visit. Depending on configuration (group size, time, and so on) a certain amount of check points in a certain order will be assigned to the player / group.
At every check point there will be a riddle that needs to be solved before being able to proceed to the next checkpoint. There will be about 5 types of different riddles (Q&A, Cryptex, Image error search, take a picture for proof, and so on).
The game is to complete your check points in the given amount of time. In versus mode the players will be able to see an approximate progress status of the other group. (no communication between groups though.)
The design as well as the finished concept will be provided to chosen freelancer.
Must run on iOS and Android (not two separate native apps but mobile web app or ideally hybrid app)
must support multi lang
must support in-app payment
must be able to invite friends to play (share game ID or similar)
must have ability to administrate check points externally (DB, web interface, similar)
must be able to determine location of player to "check-in" at check points (given proximity to location in city)

In case of any questions please do not hesitate.
