The threat of COVID-19 is forcing more and more of us to stay home due to quarantine or social distancing. As a result, we’re also often ending up with a surplus of free time. Throughout human history, people have found themselves in similar situations: lots of free time and no way to spend it with anyone. One traditional way to pass the time, in days before modern technology, was using a deck of cards to play a game by yourself.

Modern solitaire players are likely only familiar with the solitaire (or patience) games in software that comes pre-installed on their computer, such as Klondike (what people usually think of as just “Solitaire”), FreeCell, and Spider. However, with a physical deck of cards, the possibilities are limitless; there’s hundreds of solitaire games to keep things fresh. Here are five solitaire games to check out when you can’t play with a real opponent.

Black Hole: Games expert David Parlett invented this game that, like Golf, centers around discarding cards of consecutive rank. However, unlike Golf, Black Hole is much easier to win; it boasts an estimated win rate of 86%. Bridge Solitaire: Stephen Rogers contributes this substitute for Contract Bridge that’s excellent for when players can’t get together to play. It’s designed to provide a challenge to experienced Bridge players to keep their skills sharp in lieu of a partner. Forty Thieves (Napoleon at St. Helena): Legend has it this two-deck solitaire game was a favorite of Napoleon in exile. That’s probably not true, but if you want to pretend you’re an exiled former emperor while playing this game instead of someone who’s hiding out from a virus, well, who are we to say you can’t? The Clock: A game that’s 100% luck-based, meaning it’s a great way to occupy your mind when you don’t feel like thinking too hard. Its striking tableau definitely makes it unique. Pyramid (Tut’s Tomb): These days, this game is probably best known from its inclusion in Windows in the early 1990s. It features a large triangular tableau, which the player seeks to eliminate by discarding pairs of cards that total thirteen.

The pandemic has forced everyone to focus on hygiene much more than usual in recent days, for good reason. Even when you’re playing by yourself, consider upgrading to a deck of Denexa 100% Plastic Playing Cards. Because they’re non-porous and waterproof, unlike paper cards, they’re easy to keep clean and sanitary.
