Click to swap the positions of two puzzle pieces to restore the complete ancient artifact blueprint (Holy Grail, Scepter, Magic Mirror, Runestone); long press to lock up to 3 pieces to prevent accidental swapping; adjacent pieces with the same elemental attribute (fire/water/wind/earth) will be sealed and cannot be moved, and must be swapped with different elements to break the seal; there are 2 time rifts per game that can randomly reshuffle the layout; each level has a time limit of 120 seconds, and you get a base score for completing it. The more time you have left and the more seals you break, the higher the reward.
This is a casual game.
