BlackJack Math Cross Numbers

It's a very short game with 35 levels of swapping cards to get 21 as a result. You can enable the calculation to check whether your swapped cards resulted in 21. There is nothing spectacular, but also nothing to complain about this game. It's just a simple and short game, but it can be boring for some players or maybe even annoying to get the number 21 if the horizontal side matches the number, but the vertical side is not. I don't hate it, but neither do I love it. Overall, just nothing to comment about the game. Neither recommend nor thumbs down, but there is no third option for such a scenario.

This game is alright if you like mathematical puzzles. You swap cards around trying to make every row and column equal to 21 with the basic operations of adding, subtracting, multiplying and dividing. There are 35 levels that increase in difficulty. A huge problem is that when you get stuck, you REALLY get stuck, and aside from that one row not making sense, you have no clue where to start decompiling the mess. Sure, there are only so many ways that "x * y + z = 21" can be made, but if every calculation except one equals 21, you're gonna be very convinced that nothing is wrong with that row specifically, only to realize that it's part of the mistake. Most of these errors I can attribute to me being stupid, but for the very late levels, I'm convinced that you have to be a math genius to solve them. Nothing wrong with that alone, but if you make every line except one equal 21 in more than one way, this ambiguity, which was acceptable in earlier levels, may as well be your downfall in th...

Repetitive puzzle game that makes you question your understanding of basic math. The main mechanic did not feel very intuitive to me and some of the UI buttons don't seem to do anything. 100% requires to beat every level (except the last) and to test your luck to randomly get a 51 result (which will probably happen during beating levels).

Good math puzzles in a relaxing mood. The optional features of showing the totals and automatic submissions are nice too.

I liked this one rather than the first, since i only needed to develop a program when i reach lvl 27 +

If you really like number puzzles, this one is decent. You get what you pay for

fun puzzle game

A great brain exercise!

Challenging and smart game. very well designed and elaborated. The development and advancement of each level is just right. Great work from the developer very good.

I love this game. It's such a nice, yet well polished puzzle game, with good aesthetics and very calm music it makes me not want to stop playing. Highly recommend it 10/10.
