Gem Mining Robot
Read full descriptionHide full description
A casual game for a self-propelled robot that specializes in digging gems. It has enough power, and with a powerful laser launcher, it can evaporate clay and move almost unimpeded underground. It also has front and rear cannons that can destroy various monsters underground. But it must be able to fire after digging at least one gem. This robot is not omnipotent. It does not know where the gems are, nor where the monsters are. It needs your operation to complete the task. 1. The direction of advance: You need to indicate the direction of advance for it (by gently swipe to up, down, left or right) 2. When to fire: There are various monsters that can automatically track it, and as long as they touch it, the game will over. Therefore, it is best to shoot the monsters before they approach, and of course the score will be consumed. 3. Do nothing about the stone: it can only go around the stone and move forward. However, for the stone that has no obstacles in front or is at the edge of the tunnel, just push it lightly to break through the obstacles and continue to move forward. Because stones can kill all kinds of monsters, in order to save score, it is best to use stones to kill such monsters. Main operations: 1. Swipe: Slide your finger up, down, left, and right anywhere on the screen to change the direction 2. Tap: Tap the location around the robot to fire. Notes: Internet is must to play this game.

ChainSpin is a rotational puzzle game where you spin the junctions between blocks, match colors, clear the board, and create satisfying chain reactions. The controls are simple—just choose a junction and spin. But mastering the game requires you to read the board, anticipate how the blocks will move, and carefully decide where and which way to rotate. Clear groups of matching colors and enjoy the thrill of building one chain after another. Progress through a variety of levels, each with its own objectives and board layouts. The opening tutorial levels introduce the controls and game mechanics step by step, making ChainSpin easy to pick up even if you are new to puzzle games. Clearing large groups creates useful items that can change the course of the game. Use a variety of items, including Shuffle Blocks that rearrange the board when you need a new opportunity. You can also choose how item chain reactions are triggered, adding another layer of strategy to their order and timing. Your score is based on more than blocks cleared and chains created. Items and remaining moves can also earn you a clear bonus. Each level awards stars based on your score, giving you new reasons to replay completed stages and aim for a higher rating. Compete through Game Center rankings for the highest level reached, longest chain, highest score, and total stars earned. Title medals based on your progress and special celebrations at milestone levels make every step forward more rewarding. Spin, match, and chain. Enjoy an easy-to-play puzzle game with surprising strategic depth—and plenty of reasons to play again.
