Egyszerű. A biztos fekete alatt és felett kipontozod mindkét mezőt. Ez megadja a lehetséges folytatást. 80 mp a szintidő :)

The "peek at solution" feature seems to help solve it quickly.

Brian,
the peeking function appears slower than using my special solving method to this type :)

De Thomas, miért pontozod ki alatta és felette is? Oda 2 kerül egymás alá, nem csak egy!

You can start with a bit of out-of-the-box moderate lookahead

If the 2 in r1 goes in c1-2, then:
> the rest of r1 is white which
> forces in each of c3-5 the top clue to be in r2-3 (and the bottom in r4-5).
= There is no way to arrange the top 1s in c3-5 in r2-3 without the 2 in r3 causing a conflict.
Therefore the 2 cannot start in c1 and c1r1 is white.

But then I can't find a way forward without deep lookahead. (Though being a small puzzle there's a few ways to do that.)

Found to be solvable with deep lookahead by infrapinklizzard.

Looks like a frog to me. Had to guess twice.
