DiceDrop is a falling dice puzzle game where you rotate and drop pairs or trios of dice, then clear them by matching three or more. You can choose the falling pieces from pairs, pairs plus trios, or trios. Trios come in straight and L-shaped forms, so you will need to rotate and place them according to the board. Controls are simple: tap and swipe. Swipe left or right to move, swipe down to drop instantly, and swipe up to pause. Tap around the piece or near the edge of the screen to rotate the piece in that direction. What makes DiceDrop unique is that dice are not locked neatly to a fixed grid. Depending on how you move or rotate them, dice may land shifted by half a die. This small offset makes the next placement more challenging. To line things up the way you want, you need to read not only the dice faces, but also the position shifts, and sometimes adjust the offset by pushing pieces against the wall before they fall. Clearing is not limited to matching the same face. Dice disappear when three or more line up vertically, horizontally, front-to-back, or diagonally by matching the same face, a number sequence such as 1-2-3 or 5-4-3, or the same color. Diagonal and same-color checks can be turned on or off in the settings. After dice disappear, the dice above fall into the empty spaces. If that creates another match, a chain begins. Clear multiple lines at once to raise your score multiplier. Chain multipliers double with each step, and clearing the entire board in one move adds a ×4 all-clear bonus. The automatic fall speed has five levels. The faster the fall, the higher the score multiplier, up to ×5. Press and hold during play to pause and display the control areas, so you can check how each tap will move the piece. Choose your background from your photo library or 12 preset colors. The game supports 12 languages. Tap, rotate, shift, match, and clear. Read the placement of pairs and trios, build chains, and aim for a high score in this 3D dice puzzle.
