This is a neat little math game that has a mild rogue-like element to it, which adds replay value. Effectively, you get a certain amount of numbers that you can place on the board, alongside math operands (+, -, x, /) and by placing one of these below two numbers, they will combine into a new one based on the one chosen.

If the number matches the number assigned to a monster, it's defeated and you earn stars. Every round there's 2-4 monsters that spawn with varying complexity in their number and you earn stars based on that complexity, from 1-3. The trick is, when you use the math operands, the original numbers don't vanish and you have a limited amount of space on the board.

Whenever you 'level up' with enough stars, you can clear the board to start again, so it becomes an efficiency race with your numbers and operands to achieve the math needed to clear the board as quick as you can and save as many board resets as possible.

There are also 'characters' which basically are all the same aside from each one gets a unique 'thing' they can do. The Warrior can increase any number by 1. The rogue can flip two numbers (12 to 21 or vice versa) and so forth, adding a fair bit of complex play. Gets a little repetitive, as rogue-likes can, but it's a great time killer.

Wish it was on mobile tbh.
