Number Up: Coin Riser

Coin Stack Sort Master is a relaxing timed coin sorting puzzle game with soft cream paper texture background.
The game board has two rows of vertical coin slots, some slots are locked and marked with unlock numbers (7, 8, 9) to open as you progress. Colorful coins printed with numbers 1 to 6 are stacked randomly in open slots at the start of each round. You can drag the top coin of any column to move it into another empty or matching-number stack.
At the top of screen, a countdown timer counts down the challenge time, a score counter tracks your current points, and a target progress track shows your goal: gather stacks of 5, 6 and 10 matching coins to complete the level objective. Stack multiple identical number coins together to gain score points continuously.
Convenient functional buttons are placed at the bottom and top corners: yellow "Add coins" button to add new coins to slots, blue reset button to rearrange all coins, pause button on top-right to suspend the countdown timer.
If you fill slots with matched number stacks and reach the target score before time expires, you clear the round. The simple drag-and-drop sorting mechanic, bright pastel coin colors and low-pressure timed challenge make it a perfect casual brain puzzle for all ages to pass spare time.
