I am familiar with the main UK sites, like IG, Sporting Index and SpreadEx. But I am particularly interested in other sites, especially European, American and Asian marketmakers.

Thank you for any help!

I like William Hill for spreads. You can find anyway many of the best sites listed here

How much do you win at the sports book when you bet on the spread compared to straight up?

Is it worth it try to pick the winner of the spread(line) or just the winner of the game?

It depends on the line.

If you bet using just the point spread you spend $1.10 to win a dollar, Example = If you took a team whether they are the favorite or underdog, you would need to spend $22.00 to win $20.00

Now if you took the MONEL LINE The dog will give you better odds on your dollar since they are a DOG, Example +150, you will get $1.50 for every $1 you bet ( $20 bet and if the dog wins you get $30, so you will cash out a $50 ticket)

If you bet the favorite on the Money Line you have to put out more to win, like -150 you need to spend $1.50 to win $1... the same $20 bet will get you back roughly only $16, and wouuld cash out a $36 ticket.

Hope this helps,

When you bet on sports, what happens when you exactly meet the spread (instead of covering it)?

If the spread is 1 and the final result yields exactly a difference of 1, does the bookie win?

Alright it's already been answered but nobody quite answered it correctly. This happens quite frequently, and it is called a "push" - all bets are refunded.

This famously happened in a Superbowl a few years back where pretty much everyone in the casinos had to wait back in line again to get their money refunded.
