Russian Puzzles

Russian Puzzles is a series of original 3D puzzles, including Quarks, Crosses, Spinner, Square, Donut, Ring, Butterfly, Flower, Trinity, Cube, and Cuboid, which train the human brain's thought processes. "Russian Puzzles" are touch-based and consist of pieces linked by closed chains. Shuffle the pieces and try to restore their original state by rotating the chains. It's not easy. Show your ingenuity, attentiveness, and resourcefulness. Hint: Easy puzzles include Cross-30, Donut, Trinity, Spinner, Butterfly, and Ring. Harder ones include Quarks and Cross-24. How to move: Touch one puzzle piece, then another. If the selected pieces are linked by a chain, the chain will rotate, and the first piece will take the place of the second piece. How to rotate a puzzle: Touch an empty space on the screen and, without releasing it, rotate it in the desired direction. "Russian Puzzles" develop spatial, combinatorial, and algorithmic thinking, logic, intuition, and other intellectual abilities, have a positive effect on memory, coordination, and fine motor skills, and activate new neural connections.
