Some points...

There are three different tile sets: hex, square, and triangle. There are also infinite versions of each. Hex are the easiest, triangles are the hardest. Infinite repeating planes make some things much more complicated.

You start out with simple constant based rules.

    5
    ┌──────┐
    │ 4    │
    │  ┌───┼──┐
    │  │ 2 │  │
    └──┼───┘  │
       │     2│
       └──────┘3

The 5 region and the 3 region can't be resolved directly, but you can say:

    * the 4 cells within the 5 region must either be a 3 region or a 4 region
    * the 2 cells in both regions must either be a 1 region or a 2 region
    * the 2 cells in the 3 region must either be a 1 region or a 2 region

So you would create those as rules.

Later, you get to use variables (they get tricky to think about)

    X+
    ┌──────┐
    │ 0    │
    │  ┌───┼──┐
    │  │ ? │  │
    └──┼───┘  │
       │     ?│ +1
       └──────┘X

A region with X+ (e.g. 3+ which says that this region has 3 or more mines) that overlaps a region that has one more than the number of mines in the X+ (e.g. if the X+ was 3+ then the second region would be 4) and there is no part of the X+ region that does not overlap the X +1 region... and I don't care about the actual values designated by the '?'

The intersection of the two regions is either X or X+1 (3 or 4).

But that rule can be applied for a 1+ and 2 region, or a 2+ and 3... and so on.

And then you get more variables that you can use.

     +Y
    X
    ┌──────┐
    │ ?    │
    │  ┌───┼──┐
    │  │ ? │  │
    └──┼───┘  │
       │     0│ 
       └──────┘X

The X+Y region that does not overlap the X region has Y mines in it. So a region of 8 that overlaps a region of 5 (and all the 5 is in the 8) has 3 mines in the non-overlapping area.

Try the demo!

Bombe embeds a copy of the Z3 SMT theorem prover to validate that the rules you create are sound, enabling it to show counterexamples for logical inconsistencies.

People mention the UI being bad-- I think it's more that the fundamental gameplay loop is confusing, and it's sometimes hard to understand the logic behind the rules you need to make.

I like this! It reminds me of Zachtronics, specifically Exapunks. I will make sure to grab a copy. Gameplay is important to me, so I hope that it plays well. I'm curious is there is a solve state. We will see.

It's a cool idea but the UI is just too confusing

“Robots will use all the CPUs in your computer to solve levels in the background. Not only does it cut down the time to re-test all levels, it makes your room nice and warm.”

Looks cool! I especially like that the premise is so simple and so interesting.

Is there a way to play the demo online, i.e. without downloading?

Hexcells but with a terrible UI?

There's so many games like this that seem completely capable of playing in the browser. Why haven't we seen a platform like Steam for in-browser games?

The UI feels unpolished (why can't I select multiple patterns in one movement? Why is the bomb/free selection so small?) but the game loop itself is quite satisfying. I remember playing Minesweeper as a child, explaining the deductions I made to imaginary friends, and having to think through why a certain rule works the way it does scratches the same itch.

Doesn't run with proton for me.

Worst UI ever.

No, I don't need Steam, I only buy on GOG.
