These days, it's amazing how cheaply you can amass a killer board game collection if you hit a bargain time of year. This year's Prime Day offers some gems, including some of the most interesting releases of recent years, at surprisingly deep discounts.

While family and casual games tend to get most of the attention when it comes to board game deals, this year there is plenty for the more dedicated hobbyist. With that in mind, I've scoured a truly wide range of game genres this year to bring you what I consider to be the five coolest deals. [Because “King of Tokyo” is easy enough for a family get-together, while serious players will find strategic depth in the push-your-luck mechanics and power cards. The game was designed by the legendary Richard Garfield (creator of Magic: The Gathering). It doesn't hurt that the theme is appealing - who doesn't like giant monster fights?

The latest version of this game is already an inexpensive introduction to board games at its regular price, but a substantial 44% discount makes it one of the best value-for-money tabletop games available.

If you're looking for something a little more engrossing, the half-price Marvel Champions Core Set may be the catalyst for a new obsession (consider this a recommendation and a warning in equal measure). This solo or cooperative deckbuilder is a “living card game,” and while you can essentially always purchase new card sets to expand your experience, there are no randomized booster packs or other blind purchases; everything comes in the form of complete expansions.

In the core box, you start with heroes like Spider-Man, Captain America, and Iron Man and are sent into battle against villains like Rhino and Ultron. With so many expansions available to add new heroes, villains, and campaigns, it could easily become a hobby in itself. With so many expansions available that add new heroes, villains, and campaigns, it could easily become a hobby in and of itself. Solo play is also possible, so there is no need to find a group to play with.

Sometimes what you really want to do during a big sale like this is buy a big board game full of cool plastic stuff that is ridiculously impractical that you normally wouldn't dare buy. Listen, I've been there. This year's recommendation is Dissent: Legends of the Dark.

Even at 34% off, this dungeon crawler is not cheap, but the savings are substantial and you get a lot of cool stuff. Detailed miniatures, tons of cards and board tiles, and really clever 3D terrain make the game pop visually on the table more than any other dungeon crawler I can think of.

The game itself is a large, sprawling campaign set in a rich fantasy world. The app enhances the storytelling and streamlines the gameplay. The more I play board games with integrated apps, the more convinced I am that this is a great option. It makes it easier to automate villains and randomize scenarios, especially when playing cooperatively.

If you want a really cheap board game, Amazon is practically giving away 7 Wonders Duel this year. Basically, think of it as a Civilization video game played with cards. The game condenses the popular nation-building game into a tense two-player head-to-head battle, and is arguably a better and more exciting experience in the process.

It's small in size and price, so it's ready to go on the edge of the board game shelf when you want to show your customers how well you managed ancient Greece.

Let's wrap up our board game feature with one last one. In the cooperative mystery game Mysterium, you play as a group of psychics and one ghost trying to solve a murder in a haunted house. The ghost players are not allowed to speak at the table and communicate only through dream cards depicting surrealistic images.

This is a unique board game experience, enhanced by truly gorgeous artwork, and at 45% off, you'll be sure to surprise your friends at your next board game night if you add it to your collection.
