What the game is
5D Chess With Multiverse Time Travel takes the rules you already know and adds spatial, temporal, and parallel dimensions on top of them. A piece can move back in time, which creates a branching timeline, and a rook can be sent to a parallel dimension entirely. Your king exists in more than one place at once, so checkmate is no longer a single board to defend — you have to protect your kings in the present and in the past. The result is a chess variant built around time manipulation and turn-based strategy, where the board keeps growing as timelines split.
Playing together
You can play online against friends or against strangers, and Remote Play Together is supported for sitting in on a match with someone else. The interface is built so you can learn as you go: diagrams and views show how your pieces move, which matters once timelines start branching and you need to keep track of where everything actually is. If you want to sharpen up before facing other people, there is a collection of multiverse chess puzzles to solve, four different AI personalities with different strengths and styles to practice against, and a variety of starting positions and scenarios to try.
Before you start
Expect a steep curve. This is tagged as difficult, and the mental load is real: you are reasoning across several timelines and dimensions at once, tracking threats that may come from a turn that already happened. The game leans psychological as much as strategic, since a position that looks safe on one board can be losing somewhere else in the multiverse. Give yourself time with the puzzles and the AI personalities first — they let you experiment with branching timelines and parallel moves without pressure. Once the diagrams start making sense, the online matches open up.
