This guy has some good pictures and descriptions.

(Note, you say 3 lines, but then 3 phones, so not sure if you mixed up
lines and stations or not, but doesn't matter much either way. They do
make 2-line phones that can answer either line, but I haven't seen a
3-line phone that isn't part of a PBX/keyset type setup).

Daisy chaining is an undesireable inside wiring method where one
station is wired to the next (maybe to save wire and certainly to
reduce useability and reliability). The modern & preferred method
is home run (star) wiring where all stations have their own cable
back to a common point (head-end). This is where you put your 66
(or other) block. A block makes no sense in a true daisy-chain.

It depends somewhat on the type of 66 block you have.
The most common (and preferred) type is 25pr 2+2 .

It has been a while, but ISTR: You punch all the service
(incoming) lines down in proper order on the left side, and
all the station lines on the right. Then use crossconnect
on the inside teeth to loop the service around. If you have
done your spacing properly, you can also use bridging clips.

The key for your "all three phones answer" is to loop the
crossconnect from the inside teeth of incoming pair 1 to the
inside teeth of pair 1 of station one, loop to pair 1 of
station two loop to pair 1 of station three. Then either
cutoff, or leave some extra neatly coiled if you suspect
station four may soon be required.

The basic idea for all blocks is to properly terminate
all fixed cables once and for all. Never touch again.
Then run crossconnect to make the needed short-term or long
term connections between cables. This is painfully obvious
on 110 blocks where the fixed cables are slammed down.

As Robert pointed out daisy chain is not a proper term here (general
weirdness of the term aside) because you already have a central block all
your cables go to. I assume they do otherwise there would probably be no
question or it would be worded differently. Daisy chaining refers to
cabling station 3 from station2, station 2 from station 1 - a very bad
(i.e. inflexible) practice indeed.

I just wanted to mention that to implement Robert's instructions you'll
need a 66-type punch tool *without* the blade. If you got your punch down
tool in HD or Lowes and did not get extra blades, you've probably gotten a
blade that has 110-type on one side and 66-type on the other but both have
blades. The blade will obviously cut your cross-connect wire at the first
punch and you won't be able to connect those stations together in
parallel.

You can still use bladed 66-type tool if your 66 block has 4 connected
contacts per row, not the more common 2+2. You'll use 18 rows then: 4 per
each station and 6 for the incoming lines (though I could not get from
your post what you want to do with Line 3, so you may need 2 more rows for
that). This is where description gets really complicated without an
illustration (picture worth 1000 words). Try it, it will most likely be
self-evident if you have all the right parts. If not, post here if you
need better description, I'll try to draw it up
