I honestly had no idea what I was doing or what caused the game to end. After a bit of experimentation I figured there's such a thing as too many chips so I kept grabbing the biggest to then make the 1000's vanish. Time and score kept going up so I assume I was doing something right.
I don't really know what the game was trying to do, I had difficulty understanding the instructions but the sound effects were so on point that I ended up playing for 10 minutes so well done, you!
