Create and play Chess variants

Features & Capabilities

Omnichess is the game that lets you design and play your very own chess variants. With AI and online play, you can set up 2–8 players in any configuration—everyone against everyone or teams—and choose from square, hexagonal, or triangular boards.

Experiment with win conditions like Checkmate, points, tile capture, or annihilation, and fine-tune timers (Interval, Bronstein, Hour Glass) and asymmetric move times. You can alter rules (en passant on bishops, castling on any pair), and define how each piece moves, choosing from 40+ icons for pieces.

User Reviews

Users like the app’s strong chess-variant creation features and see it as one of the best iOS options for this niche, with usable AI. However, a recurring pattern across reviews shows serious stability and reliability issues: crashes, broken variant creation (save/validation), flaky online multiplayer, and frustrating UI/editor changes. Until these are addressed, the core concept remains appealing but often impractical.

Pros

Strong, feature-rich chess variant creation/editor that many users value.
Variants themselves are good and the app is considered one of the best options for iOS in this niche.
Playable AI opponents provide a usable way to test and play variants.
Indications of ongoing development and a roadmap with more features coming soon.

Cons

Variant creation workflow is buggy—saving, validation, naming, and description issues prevent saving or creating variants.
Online multiplayer is unreliable; matches fail to start or moves don’t register, and players may not respond.
App stability problems; crashes/freezes when creating variants and progress is lost on updates.
Editor/UI and controls changes hinder usability and feel inconsistent or awkward.

Can’t even make your own variant without the app freezing and crashing. iPhone 15 Pro shouldn’t be having a problem with this. At least you don’t have to pay to make your own variants like Chess Remix, but this one crashing every time doesn’t make it much different. Also, if you don’t choose to let it send you notifications (where it says they won’t spam you), it’ll spam you in the app instead that you should turn on notifications. Additionally, there is such a huge difference between the Easy AI and the Medium AI. The Easy AI literally gives pieces away, but then just one step up to the Medium AI and it’s just too much to beat.
