III. [v71-51] on 2 × 2 intersections of a 3 × 3 cm grid dots arranged with at random selected place and with the same size randomly selected from 5 sizes; black ink with graphite pencil on paper
IV. [v71-52] inside the squares of a 2 × 2 cm grid numbers arranged in groups of 4 with at random choice of 3 numbers; rub-off number with graphite pencil on paper
V. [v71-57] on the intersections of a 3 × 3 cm grid, dots with randomly selected size (5 sizes), but in columns of 1 element one element is left out at random from left to right; black ink with graphite pencil on paper
VI. [v71-76] 2 squares with randomly selected size and place, the second in size smaller than the first; black ink with graphite pencil on paper
VII. [v71-77] on the intersections of a 2 × 2 cm grid, dots in 5 sizes are arranged; the random selection of one size increases the chance with 3 to get that same size on the surrounding intersections; black ink with graphite pencil on paper
