There’s something about overcoming a huge challenge that adds a level of excitement and a sense of achievement that you just don’t see in more casual games. It’s why Myst was so popular in the early 90s, and why The Room was so popular on the iPhone and iPad.

And yet, like all games like Myst and The Room, when it’s done, it’s done. Thankfully, The Room spawned The Room 2, The Room 3, and The Room 4, but if you’ve read through the sequels and are looking for the next big challenge, here are some great puzzle games to download.

We might as well start with the free-roaming version of the godfather of all great puzzle games. The realMyst sequel to the best-selling game of the 90s was a reimagining of the original that dropped you into the 2D world so you could explore it in all its glory.

If you liked The Room but have never played Myst, this is a must-have.
