Dots and Boxes and MYSTERY BOXES Tic Tac Toe

So basically this game is a mix of "Dots and Boxes" and Tic Tac Toe

You start off by drawing 5 rows of 5 dots, and then you put one box anywhere in each row, the first row's box is labeled 1, the second row's box is 2, third row's box is 1, fourth row's box is 2. Then you play a normal game of dots and boxes, each player takes turns putting one line down at a time. When a player makes a box, they put an X or O in their box. If a player can create multiple boxes in one turn (after creating one box, if there are other areas around them they can create a box with one line) then they can create multiple boxes, but can only chose one space to put their X or O. The next player can either put their symbol in a box made by the other player, or make more lines. You continue playing the game until every square is filled, even if someone got a 3 in a row, 4 in a row, or 4 in a box.
After all the squares are filled, you flip a coin to figure out what the mystery boxes are.
If it's heads, 1's = X, 2's = O
If it's tails, 1's = O, 2's = X

Here's a game I played with a friend. (In this game, we flipped tails, making 1's = O and 2's = X
