Ruleset I made for Five Nights at Freddy's: Flipside. A fanmade trading card game and a personal celebration of this franchise of mine.

This game is an art project I've been working on and will keep working on if enough people show interest in it. I plan to make a sorta playable version in Tabletop Simulator or Untap if people really want to.

Checkout my page for my WIP cards and card templates in case you want to make your own.

I've spent weeks on redesign for this ruleset, trying to find what fits best to FNAF. The final design I set on has the simple goal of defeating all other players with rules similar to Magic and Lorcana.

The game includes characters, items and locations. It features cards that can be played during opponent's turns or set up traps to make it turly feel like surviving a suspensful night of FNAF.

In case anyone wants to read the rules as normal text:
