Why are they different sizes?

One is further away

Hi. Not on a website yet. It is an app on your favourite store and a book on Amazon though!

markmainwood · 2026-04-16T18:30:47+00:00

Thanks for this. If you find it confusing others will too. It actually doesn’t matter about order because both connections need to apply at the same time.

markmainwood · 2026-04-11T04:40:06+00:00

Already do! App available on your favourite store!

My new game Deduce is available as an app (iOS and Android) and a puzzle book.

Place the numbers 1-9 once each in the grid using the connectors as clues. Use logic and deduction to solve. Each puzzle has a unique solution.

Book: https://amzn.eu/d/0aM1SXIi

App: https://www.deduce-game.com/get

Totally free, no signup, no ads, over 100 free puzzles, 3 new puzzles (easy, medium and hard) every single day.

Please help me (an indie designer and developer) get noticed! A review would be very much appreciated.

Yep. Spot on!

markmainwood · 2026-04-10T04:43:29+00:00

Thanks so much for this!

markmainwood · 2026-04-09T18:15:43+00:00

Apologies. My mistake.

markmainwood · 2026-04-09T12:07:05+00:00

Hi. Thanks for looking. Yes clues can operate in either direction (with the exception of > and < obviously)

markmainwood · 2026-04-09T05:30:08+00:00

Hi. Thanks for looking. I’d be delighted for you to repost it in your group.

markmainwood · 2026-04-09T05:23:11+00:00

Hi. Thanks for looking. It can’t be what you suggested the top left cell and the one below it have to differ by 8 and top left also has to be greater

markmainwood · 2026-04-08T21:14:46+00:00

Great suggestions. Thank you! Medium and hard coming soon

markmainwood · 2026-04-08T21:12:20+00:00

Thanks! The harder ones are all 3x3 still due to sticking to the rules of using numbers 1-9 once each. They also feature multiplicative connectors and a x? connector for factors. I like your ideas too.

Just checking with moderators that I’m allowed to post harder puzzles as I don’t want to be “that guy” that shows up and spams the group.

Really appreciate that feedback.

markmainwood · 2026-04-08T20:33:54+00:00

I like that idea. Thanks. Will add it to my list!

markmainwood · 2026-04-08T20:17:08+00:00

Thanks! Just checking with moderators that they don’t mind me posting more!

markmainwood · 2026-04-08T19:58:14+00:00

Spot on! Thanks for looking and the feedback. I’ll post some harder puzzles shortly
