I don't think so - have tried varied amounts on all types of eggs, and nothing

I am with Edward on this, I have used multis on silver eggs but less than 100x!

There is no exact number on the win cap. I have not won with a multiplier larger than 100x on normal eggs. My usual technique is to use a 120x multiplier on bronze eggs (this actually counts as two 60x multipliers as the egg awards two prizes). Once I get the trophy I might play around with various multipliers to narrow down the specifics of the cap.

Well I used almost 3000 hammers and I don't know how many stars, used multis ranging from 2 to 600 on almost every special egg and ended up with only 101 tokens for the day. Also, I cannot ask for help to grow plants or send crates to friends today, so I have some problems !! It seemed to me that most of the tokens came from normal eggs and I only saw a one in a gold egg.

i have tried numerous times with multipliers and have gotten zilch. could have just been bad luck then.

I have personally won tokens from all the types of eggs (with the obvious exception of the prize egg). I have also successfully used small multipliers on the bronze, silver, gold and platinum eggs. The ruby eggs can also award multiplied tokens.

To clarify on the estimations of the multiplier cap, the total multiplier limit appears to be 100x. In other words:

Normal < 100x
Bronze < 200x
Silver < 50x
Gold < 100x
Platinum < 300x

This is based on my experience from yesterday so I am operating on a limited data set. This may not be completely accurate but my advise is go "go small"

The spring event was set up in a similar fashion but the token drop rate appears to be lower.

Tokens are fairly are fairly uncommon but I did manage to win around 1,000 tokens yesterday with most of that coming from multiplied wins.

@Heather: It is not, it is only taking off 2 hours. I think they recycled code from the Spring event which did take off 4 hours and forgot to change the text. This event appears to have been "balanced" to make it a bit harder to win huge number of stars/hammers/multipliers from plants.

This really bothers me because I am in the volcano area and the multiplier purchased is 120. The limit is lower than the multiplier I can purchase. I personally feel the levels should equal. If the multiplier you can purchase is 120 - then the limit should be set at 120. This really stinks....
