Base 5

Base 5

Your main goal is to make a number that’s a multiple of 5 (like 5, 10, 15, 20, or even negative ones like -10). The only rule is that the final number can’t be zero.

You start with the “Current” number shown at the bottom—in this case, it’s +3.

Then, just pick any number from the 3×3 grid and add it to that +3.

The example in the picture makes it super clear: They pick the number 12 from the grid.

So, you take 12 + 3, which equals 15.

Since 15 is a multiple of 5, that’s a winning move! Simple as that. You’re just trying to find the right partner in the grid for your current number.
