Games in which it is necessary to lay out different coloured jewels belong first of all to the category of connection 3, i.e. the current of eliminating identical elements located next to each other. The creators of the free GemHEX game, however, had greater ambitions.

The result is a real puzzle with combining, where you have to click to get a specific result. The title teaches mainly how to associate facts and establish the order of events. The screen is always divided into two parts.

On the left we have a set of jewels. On the right-hand side there is a diagram according to which they have to be placed in order to finish the level. The game is supported entirely with the mouse.

A click on one of the lights will replace it with another precious stone (in the order shown in the middle of the screen above the reversing and restart buttons) and all adjacent stones. As long as the clicked item turns into the next one in the queue according to a clear plan, the side ones already jump by two types of jewels. It is important to keep in mind that orange amber can't turn into anything else, so it will simply disappear from the board.

These at first glance complex, but in practice very trivial dependencies should be well used to achieve the intended effect.
