Dad here:

Today, after school, as we're walking into the house, LB tells me that he wants to play two games. One is candyland, the other is a secret.

Turns out the secret is Labyrinth (we have Labyrinth Jr. as well, but he plays the bigger version just fine, though he's not mastered the strategy yet...). As we start to set up, he tells me there's going to be some new rules and we need to cut out some squares of paper. He procedes to write the numbers 1 to 10 on the paper squares and has me write the name of the game across the top. The rules are, we shuffle up the squares and we draw and the number is the number of squares we can move after we slide our tile. The game ends when the draw pile is exhausted (or, as he puts it "We each get five moves") Otherwise the game mostly follows the rules if the game (I don't recall splitting the objectives deck into equal decks for each player, but with the other rules that doesn't affect much, since the game won't last long enough to exhaust either.) For the second game we played, he added one round for himself afterwards (I think he just wanted to get one objective reached during the game. He had gotten 2 in his five turns the first game.)
