Animated Puzzles Star

As it's a turn-based game, if you need the faster way, simply create a profile at Win 10 with your backup gamertag and once you start the game, you can invite your main gamertag and by switching profile to take turn, it take me around 15-20 mins to win the match (just mismatch few for your backup gamertag then try to match correctly for both side).

You will also unlock

BTW, at both Win10 mobile and desktop, i keep encounter error message when sending invite but it actually SENT successfully.

You'll need to have a friend on Xbox Live who will either play through a match with you, or who won't do anything and allow you to win as the timer runs out after 72 hours. You will also get the following achievement for starting a battle:


If you're going to go the multiplayer route, go to the battle tab on the left side of the main menu and invite your friend to a match (alternatively, if you were already invited by your friend, click the play button (the match will be listed under the your turn column)). I would recommend setting up a match on one of the puzzles from the lower tiers because it appears that those have fewer puzzles pieces to complete the game.

The key is to get more points than your opponent - it does not matter who finishes the puzzle. You will be taking turns trying to finish the puzzle. The game makes you go in blind (ie you can't see what the completed puzzle looks like) so correctly placing a piece nets you one point. It does not matter who plays the last piece and completes the puzzle, the person with the most points at the end of the match wins.

You do not have to be in the match the whole time. When I completed this achievement, I was working on other tier puzzles to grind out other achievements while I waited for my partner to finish his turn. If your partner moves quickly though, you can just sit in the game and wait for them to finish their turn too. My partner also played a few pieces correctly here and there to speed things along. Once you've won the match and the puzzle is complete, you will get the achievement. Happy hunting!

UPDATE: Thanks to K4rn4ge, SnapDragon, CjhCarter vL and TangerineGamer for confirming this - you can start a match with somebody you know doesn't play this game or who doesn't even own a Windows 10 device, play your turn, allow the timer to run out and still get this achievement! Since you'll have more points at the "end of the game", you'll win the match after 72 hours once the timer has run out. You also don't have to be in the game for the achievement to pop either.
