Over the last couple of years I have been introduced to two card games with a similar theme - co-operating to play numbered cards in an increasing sequence - but with very different approaches. Hanabi, described in this article (Part 1), is a game of deduction - it echoes classic puzzles featuring multiple logicians reasoning not only about what they know themselves, but what they can deduce about what the others know based on what they say or do. The Mind, on the other hand, is a game of group rapport and intuition, and will be discussed in Part 2 of this article. ...

I recently discovered Inform 7, a tool for creating text adventure games easily in (semi-)natural English - in this article we see how Inform 7 can be used to implement a small text adventure, and some interesting features of the language along the way. The game is based on MINI, an example adventure in Peter Killworth’s How To Write Adventure Games for the BBC Microcomputer Model B and Acorn Electron (1984). And, after the discussions on how to fit games into small amounts of RAM in my previous article, we shall see how the size of the game varies between BBC BASIC and Inform 7. ...

I recently picked up my battered copy of Peter Killworth’s How To Write Adventure Games for the BBC Microcomputer Model B and Acorn Electron (1984) from my bookshelf. This was intended to allow the reader to write text adventure games of the style “GO NORTH”, “TAKE SWORD”, “THORIN SITS DOWN AND STARTS SINGING ABOUT GOLD” - a genre nowadays generally referred to nowadays as interactive fiction. But looking at it now reminded me of the challenges of writing these adventures then, and prompted me to explore how these have changed in the intervening decades (especially with increasingly sophisticated authoring tools) - and how these challenges relate to the concepts of accidental and essential complexity in system design. ...

As my mind wandered while assembling some flat-pack furniture, I was (perhaps inordinately) pleased with myself for coming up with a riddle about one of my favourite playwrights. ...

Introduced to Horde Chess, a chess variant where Black plays as normal against a White side with 36 pawns, handily available to play online at lichess.org. (White wins by checkmate, Black wins by capturing all the White pieces.) ...

I recently compiled a quiz based on the openings of a variety of books on our bookcases. It is a mixture of the well-known and the slightly obscure, the literary and the popular, with a dusting of SF/fantasy sprinkled in. This page has the questions only: when you’re ready, there is a version of the quiz with answers also available. ...

When deciding which home assistant is best, a key test might be “OK Google/Alexa, tell me a maths joke”. (OK, your priorities may vary.) Alexa has a variety. Google has only one, and that is “How do you keep warm in a cold room? You go to the corner, because it’s always 90 degrees.” ...

I played a bit of chess at school, up in the eaves of the maths department, but hadn’t touched it in years before recently installing the Droidfish app (powered by the Stockfish chess engine) on my phone. Trial and error - and a bit of reading to refresh rusty tactical basics - soon discovered the (still embarrassingly low) percentage strength setting to result in a fair-ish game rather than a wipeout. But I was puzzled to find that, on occasions when I ended up in a hopefully-winning position in the endgame, Droidfish started making arbitrary, pointless moves rather than trying to make life difficult. (Puzzled, but amused when it means I can effortlessly get a bunch of pawns promoted and checkmate with three queens or the like :smile: ) ...
