# Numeric Stack

A rapidly developed puzzle game for Puzzle Jam [8 Bits to Infinity].

Your objective is to **get rid of all numbered blocks on your playing field.** On the bottom of the screen, you see a **sum** on the left side. You get rid of blocks by painting over blocks with your mouse, so that the sum of blocks matches the sum on the bottom of the screen. If you select multiple blocks, each block should be adjacent to some other selected block.

Watch Puzzle Jam [8 Bits to Infinity] Feedback Part 1 from MrJoshuaMcLean on www.twitch.tv

I like the idea of a math puzzle. I thought it was too easy but maybe I was just lucky. There is a lot of potential here, and this game would fit on a mobile if you just make the screen smaller and remove all the black empty space.

Great work. I could see this being a pretty fun mobile game. I do think increasing the size of the boxes would be nice. The controls can be a little unresponsive feeling at times, not clearing the first time I highlight the answer. But over all fun and tough.

The controls aren't always responsive, but I enjoyed the puzzles. It's a very simple, intuitive concept but surprisingly deep in terms of variety of puzzle design. Two little things: The numbers are quite hard to read at times, and the "Next" button is rather small given how important it it.

As an after-school math instructor, this is the kind of game I wish teachers assigned instead of addition practice sheets. (Though it would need to be a lower difficulty of course.)

Thanks for your feedback!

I could indeed make the grid a bit smaller and respectively numbers a bit larger. The original plan was that I'd have larger puzzles, but turns out even smaller ones were just about challenging enough, so it served no purpose.

I also considered a glowing effect for the NEXT button when available, but due to time constraints wasn't able to implement that. You are entirely right on the fact that it is not as visible as it could be.

Difficulty is a tricky thing. I did try to assess puzzle difficulty with some weighted, more or less objective metrics, e.g number of moves to solve, ratio of winnable states in relation to all states, total block count. Interestingly enough, it seems that it is easier for me to create difficult-to-solve puzzles than non-trivial yet easy ones. The question of metrics is also tricky, as there still are some puzzles which I think do not exactly represent their position in the difficulty-sorted list.

I really enjoyed it!

I love this. The level progression is great and it's a really addicting math puzzle.

Thanks for the feedback! It took a fair while to adjust the level progression, and I wasn't even at this point quite sure it was appropriately measuring difficulty.. glad to hear it is in the right direction :)
