Being snowed in is never ideal, but it does allow for some good days indoors. While you may go outside to sled and hang with friends, there are other options.

One thing you could do is play a board game.
Here are some games you could play on a long snowy day.
Monopoly is a great game to play with family or friends, but be careful not to play with any cheaters. Monopoly is a game about business. You have to manage your money and buy properties and houses. The point of the game is to make everyone else go broke. You start off with a certain amount of money, and it is up to you to see how the game goes from there. You play with dice and have “Chance” cards, and if luck is on your side, then you will have a fighting chance. Monopoly also has strategy. If you know what properties to buy and how to spend your money, then you are going to set yourself up for a win.
If you like murder mysteries, then you’ll love Clue. Clue is a game about being a detective and reading other people. There is a murder, and it your job and the other players’ job to figure out who was the murderer, what was the murder weapon, and where the murder happened. You move to different rooms and different passageways, each having clues among them. The more clues you get, the easier it will be to solve the case. The winner is the first to correctly figure out the murderer, room, and weapon.
Some board games have a sweet spot as well. Candy Land can be a fun family or friend game as well. Everyone starts at the same spot and your goal is to follow the path to Candy Land, but some spots you land on could move you ahead or take you back to the very beginning. This game contains cards, and each card has a color. Depending on what color you get is how many spaces you move. There are also sweet characters in the game that you can pass and move more spaces. This game would be great with some hot chocolate as well.
For everyone who is good with words and spelling, Scrabble is a great game to play. Scrabble is a game that tests your mind and shows off how wide your vocabulary is. You start with seven different letters on your tray and start building words from them. As each person takes a turn, you get points depending on how big your word is and how many letters you use. The goal of the game is to not have any letters left and to have the highest score.
