Endangered Rescue: Lemur Leaf Frog is part of the 18Escape line of games, each of which pack a full escape room game experience into a tiny package! As a group, you will solve a series of puzzles to unravel a mystery. Puzzles may test your perception, wordplay, and lateral thinking. English language fluency is required. When you have solved a puzzle on the cards, you will enter the answer into the companion website (compatible with all smart phones and computers), and it will check whether you are correct. If you are, the website will tell you which card or cards to take next. The website also contains a graduated hint system, so if you get stuck, you can get just a small hint about the current puzzle to get moving again without giving too much away.

This system is non-destructible: Some groups may choose to write on cards, but this is not required. A group cannot replay the game, but they can pass it on to another group. This entry in the series takes about an hour to solve, and it is rated 1 out of 3 in difficulty.
