VexaMerge

Welcome to VexaMerge, a logic-based puzzle game that combines strategic placement with a unique mathematical twist. In this game, your goal is to merge numbers on a 5x5 grid using a unique prime number transition system.

Core Gameplay:
You are provided with numbered hexagonal tiles at the bottom of your screen. Drag and drop these tiles onto any empty cell in the 5x5 grid. When a placed tile matches the number of an adjacent tile (up, down, left, or right), they merge. Instead of simple addition, merging identical numbers generates the next prime number. For example, two 2s merge to form a 3; two 3s merge to form a 5, and so on through the sequence of prime numbers (2, 3, 5, 7, 11, 13...). Plan your moves carefully to trigger chain reactions and manage the board space.

Game Modes:
1. Main Levels: Challenge yourself across 50 progressive levels. Each level presents a specific target prime number that you must synthesize within a limited number of moves. Some levels feature pre-placed tiles as obstacles or starting points.
2. Chaos Sandbox: An endless mode without move limits or specific targets. Try to reach the highest prime number possible before the board fills up. Be prepared for random variations, as the prime merging rule will occasionally be temporarily replaced by standard addition (e.g., merging two 5s results in a 10), adding an unpredictable twist to your strategy.

Features:
- 50 challenging puzzle levels with increasing difficulty
- Endless Chaos Sandbox mode for continuous play
- Clean, minimalist interface with smooth hexagonal tile animations
- Local progress saving via shared preferences
