Diversifiers are a great way to add a little more fun or challenge to your jam weekend. Sometimes they can be very helpful to limit your scope or refine your ideas. They are totally optional constraints you can choose to add to your GGJ Online game alongside the main focus of the theme. It can help your game stand out from the crowd, and you can choose up to 4 when you submit!


A11yversary* - Celebrate 10 years of accessibility diversifiers at GGJ by copying the features of Team Epic Wedgie's game from 2011 - include a tutorial, no reliance on sound or color alone, and one button controls. 

*In 2011 the Orlando site ran an accessibility challenge, that was the first time accessibility had been properly considered at GGJ and was the precursor to the accessibility diversifier category. The game that won it was by a team called Team Epic Wedgie, so this challenge is to implement the same feature set that they did in their GGJ game 10 years ago

Kitchen sink - Players have a choice between at least three different types of input device (e.g. keyboard, controller, mouse, eye tracking, potatoes)

Spinal Tap - The game has separate volume sliders for different types of sound effects  (e.g. footsteps, gunshots, ambience, engine, tyres)


Are we ASCIIng too much? - All the graphics in the game must be represented by ASCII. 

Double Take - Have moments in your game that have a different meaning when seen from another angle (like an ambigram).

Photograbetry - Go for a walk, collect/photograph 3-5 found objects, incorporate them into your game.
