I got that 59% of the games are solvable in 3 or fewer guesses using the optimal strategy. (I'll take a look at my calculations later.) All my cases have some tricky part, so I had to use a piece of paper to analyze what to do in the next step.
I found also a simple strategy that involves playing always fixed numbers in the fist and second step, and then thinking a little for the third step. This is easier but guaranty only a 32% win rate in 3 or fewer guesses, and 100% in 4 or fewer guesses. (But I didn't follow alllll the cases for this strategy, there is a tiny chance that I missed a better combination of initial numbers.)
As I said, it's an interesting game and I had to use some time to get the optimal strategy. It's not too easy, but not too hard.
PS: I second the feature request of rawling to move the 0 to the right.
PS2: It would be nice that "close" and "warm" has more contrast.
