Our take on VOI

The single-page presentation and narrow XOR mechanic keep the focus on shape manipulation, but sacrifice conventional navigation controls and broader puzzle-system variety.

What is VOI?

VOI is a minimalist puzzle game based on XOR logic.

It presents four combination rules: 0+0=0, 1+0=1, 0+1=1, and 1+1=0. Each level provides draggable geometric forms, including triangles, squares, rhombuses, and parallelograms. The objective is to combine the pieces until they produce a target shape. Levels appear on one page, with mouse-wheel scrolling used to move through them. Music and sound effects accompany the puzzles.

How VOI plays

01XOR Shape Rules: The puzzles use four stated binary combinations to determine the result of joining forms.
02Draggable Geometric Pieces: The available forms include triangles, squares, rhombuses, parallelograms, and similar shapes.
03Mouse-Wheel Scrolling: Scrolling with the mouse wheel moves between levels.
04Music And Effects: Music and sound effects accompany gameplay.
