Zingoloo

Zingoloo is an educational and interactive drag-and-drop puzzle game for iOS that challenges users to match numeric values to tally marks. It’s designed to improve number sense, visual counting, and logic skills in a fun, animated, and visually engaging environment.

Each level displays 4 cards, each showing a randomly generated tally mark. Below these, 4 draggable numbers appear. The player’s task is to drag the correct number into the circle below the corresponding tally card.

Gameplay Mechanics:
• Tally cards are laid out in a 2x2 grid, each showing a tally count.
• The correct number must be dragged into a circular drop zone on each card.
• If the number is correct, the circle turns green, the number animates into place, and a feedback appears.
• If incorrect, a animation plays and the number returns to its original spot.
• Once all 4 matches are made correctly, the player automatically advances to the next level with a level-up animation and score update.


Features:
• Randomized Tally Values: Each level uses fresh values between 3 and 15.
• Positive Feedback: Correct matches show success animation; incorrect ones return the number and flash red.
• Scoring System: Score increases by 10 for each level completed.
• Progress Bar: Indicates level progress (scaled from 1 to 10).
• Dynamic Labels: Score and level labels adjust dynamically each round.
• Hint Button: Highlights the correct drop circle once per round with a pulsating green animation.
• Next Level Button: Manually restart the level anytime with “NEXT LEVEL”.
