We see a stamping in six colours. The die is used to determine the color: black (1), yellow (2), red (3), purple (4), blue (5), green (6). The number of eyes determines not only the color but also the number of times stamped. 1 = black stamped once, 2 = yellow stamped twice. If the same color is thrown again in succession, a white space is included. Henk works from left to right and then continues on the next line. Of course, the result is accurately counted.
