Welcome to Card Slots – a satisfying tap-to-sort puzzle built around smart sequencing and color matching. Tap the currently available cards to send them toward the colored targets above. If a matching target is available, the card automatically moves into its place and clears the target. But choose carefully: if there’s no matching target, the card is sent to the temporary slots in the middle. Fill those slots with the wrong cards, and you may run out of space. Watch which cards are available, plan the order of your taps, and use the slot area wisely to clear every card. Features: -Simple one-tap controls -Layered card-selection puzzles -Color-based target matching -Limited temporary slots that add strategic depth -Easy to understand, increasingly challenging levels Can you find the perfect order and clear every card?

Let’s start! Move the colorful blocks through the color-matching gates, crush them, and let the pieces on the conveyor fill buckets of and melt. It’s that simple! Are you ready for this relaxing and ASMR puzzle challenge? > Hold and drag the colorful blocks on the board and guide them through gates of the same color! > Blocks that pass through the gates break into pieces and move onto the conveyor! > Pieces on the conveyor fill the buckets of the same color and melt away! But keep these in mind: > Each block has a number on it. This number shows how many pieces will go into the bucket when the block breaks. > The numbers on the buckets show their capacity. > You can see the conveyor capacity at the bottom of the board. As more pieces collect on the conveyor, this capacity fills up—don’t let it overflow! Easy to play, fun, and a great puzzle experience is waiting for you. Can you complete all the levels?
