Dgomok21 is a japanese program which contains 100 renju problem positions, where black is in turn and has to find a win.

Black has to make 5 in a row using exactly 4 stones, i.e. making a threat followed by 4x3. For example, making a 3 followed by a 4x3.

When you are successful, the man will bow down, but if you fail, you will get a finger!

If you solved the problem, click the upper-right-hand button to view next position. The upper-left-hand button will show the previous position.

If you failed, click the lower-left-hand button to repeat the same position.

The lower-right-hand button will exit the program.

Good Luck!
