Nikita, Vlad and Mom Play with colored cubes

Nikita, Vlad, and their mom are playing with colored cubes. The cubes come in three different colors: red, blue, and green. Each person has their own set of cubes.

Nikita has 10 cubes in total, and they have more green cubes than red and blue cubes combined. Vlad has 12 cubes in total, and he has an equal number of red and blue cubes, but fewer green cubes than Nikita. Mom has 15 cubes in total, and she has the most red cubes out of the three, but fewer blue and green cubes than Nikita and Vlad.

The three of them take turns building towers out of their cubes. They can only use their own cubes, and they can't use the same cube twice in one tower. They also can't mix colors within a single tower - each tower must be made entirely of one color.

Nikita starts by building a green tower that's 4 cubes high. Vlad builds a blue tower that's 6 cubes high. Mom builds a red tower that's 3 cubes high. They continue taking turns until all of their cubes have been used up.

In the end, they count up how many towers they've built and how high each tower is. They also compare the total number of cubes they used and the number of cubes of each color. Overall, they have a lot of fun playing with the cubes and using their creativity to build different structures
