Color Hoop Stack is an entertaining and stimulating puzzle game that demands you to arrange hoops of the same color in separate piles. Although this classic game is popular among children of all ages, the online version on Greatmathgame.com offers challenging levels that become progressively difficult. Bear in mind that you can only place hoops of the same color on top of one another or on vacant spaces. Additionally, each slot can only accommodate four rings at most. Initially, the game will seem easy; however, it will become more demanding as you advance and more than five different colors are introduced. Enjoy playing Color Hoop Stack! To play, simply use your mouse.
