Tools and games

API Client lets you try requests against any API, including the Nubo API, and five classic games are included for a break.

Which apps are in this family?

App	What it does
API client	Build, send and test HTTP, GraphQL and WebSocket requests in your browser, with collections, environments, scripts and a collection runner.
Chess	Play chess against the computer, a friend on the same screen, or a private online game, with clocks, move review and PGN export.
Backgammon	Play backgammon against the computer, a friend on one device, or online with agreed dice, an optional doubling cube and clocks.
Checkers	Play American checkers (English draughts) against the computer, a friend on one device, or online, with clocks and PDN game export.
Solitaire	Klondike with draw-one or draw-three and Vegas scoring, plus Spider in one, two or four suits. Stats can sync to your account.
Sudoku	Sudoku that grades puzzles by the logic they need and explains each hint, with undo, pencil marks and a daily puzzle.

What are the limits?

• API Client’s request relay for outside addresses is switched off in production for now, and the app shows a clear message when a request needs it. See API Client.
