Kimberly,
 
Chrononauts is definitely a more complicated game then Fluxx, 
Aquarius, and Cosmic Coasters, but after you understand it you will see 
that it is not overly complicated. However it does contain a unique and patented 
gameplay mechanic for handling the timeline. So please don't feel stupid that 
you don't immediately understand it. It's one of those things that are much 
easier for someone to describe/teach face-to-face then via typed 
words.
 
By the 
way, you can find an online description of how to play here:
 
But I 
will try to explain the timeline and patching mechanics a 
bit...
 
 
There 
are two types of cards in the Timeline:
    Linchpins (purple) & Ripplepoints 
(blue)
 
Linchpins have a box on them labeled "Ripples" which lists the 
years/cards which can be affected by this Linchpin. All of these affected 
years/cards will be Ripplepoint cards. The Linchpin also shows 
a black Icon used to indicate this normal state of this year/card. 
The reverse of the Linchpin also has the "Ripples" box, but shows the 
Icon in Red with an additional Prime mark (apostrophe) to indicate that it is 
the non-standard history/version of this year.
 
Ripplepoints have a section on their front which reads "Paradoxed if" 
which shows one or more alternate/red Icons from Linchpins connected with either 
"and" or "or" statements. These will show you how to know when to flip this 
card. It only flips (becomes paradoxed) if the truth statement of 
Icons evaluates to True. The back of the Ripplepoint cards shows the 
Paradox image and reads "Restored if" and shows the negation/opposite of the 
Truth statement which was on the front of the card.
 
 
There 
are also two types of cards that you can draw and play which can directly effect 
the timeline:
    Inverters (yellow) & Patches 
(orange)
 
Inverters are used to directly flip **Linchpins**. Inverters can NOT be 
used to flip Ripplepoints directly. However, as described above, when a Linchpin 
is flipped it can affect Ripplepoint cards which may then cause some or all of 
those Ripplepoints to then become flipped as well. Some Inverters can only be 
used on specific Linchpins, others only on already Primed/flipped Linchpins, and 
others can be used on any Linchpin.
 
Patches will indicate which year/timeline card they apply to, and will 
read "Nullified if" and will show the same Truth statement as the "Restored if" 
statement on the Paradoxed side of the associated Ripplepoint card. Patches 
are played onto (on top of) the timeline cards to fix that Paradoxed 
year. They can only be played on the indicated Ripplepoint card if the 
conditions are such that the Ripplepoint has been flipped over/paradoxed (and 
therefore that the patch will not be nullified). The year 1945 also has an 
additional stipulation as there are 3 different patches, each of which can only 
be played under specific circumstances. This is a special case 
situation.
 
 
So to 
sum it all up with an example...
If you 
start with the initial time line setup, and you want to play a patch on 1868. 
Here are the steps you must take (assuming no-one interferes with your 
plays):
Play 
an Inverter to flip 1865 (Saving Lincoln from assassination)
        1865 
says that it Ripples 1868 & 1974
    Looking at the years rippled by 1865 you 
see:
        
1868 says: Paradoxed if 1865'(prime/red)
                
so it flips immediately to the Paradoxed side
        1974 says: Paradoxed if 
1865'(prime/red) and 1963'(prime/red)
                
stays normal since 1963 is still 
black/normal/not flipped
On 
your next turn, you can then play your 1868 Patch card onto the 1868 
Paradox
        
assuming that no one else has reverted 
1865 to the normal history since your last turn
 
By the 
way, you can also find another example on the online rules page 
at:
Also, 
assuming that you have played your 1868 patch as above, if someone then plays an 
Inverter to Restore 1865 to the normal history (Lincoln Assassinated) then your 
patch which reads "Nullified if 1865(black)" is then moved off of the timeline 
and into the discard pile, and then the Paradoxed 1868 which reads "Restored if 
1865(black)" is then flipped back to it's normal history (Andrew Johnson 
Impeached). 1974 will also be set back to the true/black history if it has been 
paradoxed by this time.
 
Hopefully this has helped to illustrate some of the main mechanics of 
playing this game which I am sure you will grow to love once you have a better 
understanding of how it works.  :^)
 
Also, 
I hope that I got all of my details correct as I don't have my deck in front of 
me, but have been using the Looney's website as my guide to some of the card 
specifics & wordings. But the images are a little hard for me to read 
exactly.

  I finally purchased Choronauts. It looks confusing...... Some timeline 
  events say that if the previous card isn't turned over the paradox reverts (It 
  says RESTORES IF-and has the symbol for the unfliped card- so if the card it 
  shows in the corner hasn't been flipped to red then the card I need to paradox 
  can't be flipped yet?). So does that mean if we want to flip over the card we 
  have to flip over the one before it first? 
   
  did that make sense?
   
  I am so confused on this game. It makes me feel stupid.
