InkBall

InkBall is a video game developed by Microsoft for the Windows family of operating systems. It was first released in 2002 as a game for Windows XP Tablet PC Edition, but could be played on a regular desktop version of Windows. It was included in Windows Vista and removed in Windows 7.

The Game

The goal of InkBall is to draw lines to navigate different coloured balls into the correct holes under a time limit. There are five different game modes, "Beginner", "Novice", "Intermediate", "Advanced" and "Expert".

In the Windows XP version of the game, the mouse cursor is hidden by default. You can show the mouse cursor by pressing the Alt key twice. The mouse cursor is shown by default in Windows Vista.

Walls

Solid walls: Deflects balls, always grey.

One-way colour-filter wall: Deflects all balls of a different colour that approach it from any direction and any balls of the same colour that approach it from the opposite direction of the arrow. Does not deflect balls of the same colour that approach it in the same direction as the arrow.
Clock wall: Alternates between disappearing and appearing as a solid wall which deflects balls.
Keyhole wall: Disappears temporarily when touched by a ball that is the same colour as the wall.
