What has changed: While the game platelets in the original really remind one of a kind "Mini-Tetris", they see the new more like parts of a honeycomb.
Now considering the color of the plates, which is placed so no dice.
The reward at the end of the turn has changed: It is determined in part which receives gems you and have different valences. Ultimately wins, who scores the most points values (so it will no longer be collected after colors).
The time until you have the field covered completely and correctly, has increased. The sand in the hourglass trickles slow considerably, which also appears to be very necessary.
What's left: The training of spatial vision, which is for this game a decisive advantage. Who to the effect but has greater difficulty likely quickly lose the fun of the game.
