For everyone who wants to run coinathlon, this should be the fastest games. Have "Leafboard Hoard" and "Silver Lining" as your first games. Leafboard Hoard should give nealry 120 coins and Silver Lining should give more than 160, so you need 2 games instead of 3. With enough luck, you can have over 100 coins with "Tiles and Tribulations" and "Cheep Cheep Reach". "Pinball Brawl" CAN give you dozens of coins too, but it normally DOES NOT happen.

When you do a 10 rounds game, try to be as relaxed as possible, because the last 3 rounds will cost you a lot of energy. Don´t try to hurry up, just try to finish it then.

Have fun with the RNG LOL
