Chrononauts is a fast, exciting, multi-layered time travel card game for 1-6 players. The huge deck of 140 cards features a unique 32 card TimeLine deck that's used to track ripples and paradoxes.
Players become time travellers, seeking to return to their original alternate realities by changing history (done by preventing assassinations, averting disasters, and so on); or you might choose to go for victory by collecting up the right combination of amazing artefacts.
If things just aren't going your way on the timeline or with the artefacts, you can always win by doing your duty as a time repair agent, fixing paradoxes.

Number of Players: 1-6.
Ages: 11 to adult.
Game Length: 20-45 min.

Contents: 140 Cards and Instructions.

From the back of the box:
So, you want to be a Time Traveller?
Messing with history can have its consequences. For starters, your reality no longer exists. Then there are the paradoxes - holes in the space-time continuum that threaten to destroy the entire universe. Can't find your way back to your original reality? Then maybe you can win by collecting the right combination of amazing artefacts that only a chrononaut could acquire. So shuffle up this time-machine-in-a-box and start changing history!
