Choose a Palette

Resolution

Games must have a resolution of 84 x 48. It is recommended to scale the game's resolution up so its playable but the base resolution must still be 84 x 48. Your game can be either landscape or portrait. The Nokia 3310 was incapable of sub-pixel movement and sub-pixel scrolling so it is NOT allowed. This means all pixels must be perfectly aligned with the pixel grid. There should be no half-pixels even while moving.

Game Engine

Any game engine is allowed as long as you can set your game's resolution to 84 x 48 or limit the number of pixels the player sees to 84 x 48. It must also be able to use the provided palette.

Sound

To most accurately represent the sound the Nokia 3310 was capable of, please use the sound resources available for download on the official itch.io resource page. There should only be one audio channel and one sound played at a time. So if you have music playing and a sound effect is played it should interrupt the music, not play over the top of the music.

Controls

Games can have a maximum of 12 controls (the Nokia 3310's keypad). Controls can be mapped to a numpad but it is recommended you offer alternative mappings like arrow keys or WASD so people without a numpad can still play. Mouse controls are only allowed if you are interacting with a simulated keypad on-screen. Otherwise, all controls should be on keyboard.

Ranking

Games will be judged by submitters and contributors via itch.io's rating queue system. After five games from the queue have been rated the ability to rate any game will be unlocked. The top three games will be featured on next year's jam page. The first place winner gets an exclusive "Nokia Jam 5 Winner" title in the Nokia Jam discord server.

Games will be rated based on these three categories:

Innovation

How unique is the game's design? What was the developer(s) able to accomplish within the restrictions?

Quality

How enjoyable was the game? Were there any bugs or crashes? How are the visuals / visual clarity? 

Completeness

Is audio present? Does the game feel coherent?

Optional Theme

The optional theme is: Fast & Slow

A classic racing game. Speeding up and slowing down time. Make the soundtrack Tokyo Drift (Fast & Furious) in Nokia 3310 beeps. A snail trying to cross the highway. A cooking game. Interpretation of the theme is up to you!
