Write a storyline for a game app

Hi Copywriters!

This is a creative writing opportunity!

We have created a game app called Choker (which merges chess and poker). It's a free to play - just for fun game (ie petend money). You can find it on the Apple App Store or Google Play Store.

We want to create a storyline within the game whereby players travel to different cities and take on top chess Grandmasters and high stakes Poker players at Choker. It will almost be comic strip-like...they arrive in a city, your copy would set the scene, explain the challenge, who they will face ("the Boss"). When they complete the challenge in one city they fly to the next. There are 7 cities.: Rio de Janeiro, New York, London, Berlin, Moscow, Dehli and Macau.

One other thing, the copy will need to be translated into Spanish and Portuguese so we want to avoid it being too complicated or idiomatic. Also its a global audience so we want simplistic English...maybe in the style of an adventure story for 10 - 13 year olds. Fun, exciting, pacy not too complex.

Please only respond if a) you have excellent command of the English language and secondly you can write great storylines

Let me know and thanks
