About Quantum Chess

Dive into the strange world of quantum mechanics in the game of Quantum Chess, the game you saw in Caltech IQIM's "Anyone Can Quantum" where Paul Rudd beat Stephen Hawking. With the addition of the Quantum Move players can position a single piece in multiple locations on the board at once! This puts a whole new spin on standard chess strategy, and allows everyone to get hands on with quantum phenomena like superposition and entanglement. Play against the computer, or pit your new found mastery against your friends in an Online match.

- Requires registration to play at all (even offline), - The online servers are a barren wasteland. - The offline AI was removed for rework in 2022 and never put back. Not worth 20€ in any imaginable way, it's a scam.

The game had stayed in my wish list for years, I did not buy it because people said the AI sucked. And after years of waiting they finally have an AI start enough to make the game interesting.

Completely changes the strategies of chess without changing the strategies of chess. I really like games that change the way I'm thinking about a problem, and this game does that. My one critique is that there's not a good one player mode. I can't wait until it gets a good CPU opponent is made, but I understand the development of that kind of AI is hard, about as hard as making the first good chess AIs in the 1990s.

An interesting combination of the strategy of chess with quantum mechanical effects, in addition to adding a probabilistic element into the game, one can also explore effects of interference and entanglement, and I can't wait to see what strange & wonderful strategies chess players more expert than me will develop based on this game's unique and fascinating mechanics.

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.

Games like Titanfall 2, for the pilot or for the Titan

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.

It Takes Two cannot be played alone, and that is the whole design. Games like It Takes Two that give each player a different job — including one that makes do with a single pair of hands.
