MatchMint vs Skyscrapers Logic

Tap two or more touching tiles of the same colour and they clear. Tiles above fall into the gap, empty columns close up, and — the part that changes everything — nothing ever refills. Every clear is permanent. Take the biggest group on the board and you might orphan the tiles around it, and an orphaned tile is stuck there for the rest of the round. MatchMint isn't about tapping fast. It's about the order you clear in. THE BOARD DRAINS No falling blocks. No endless refill. No timer counting down at you. The board you start with is the board you have, and your job is to empty it. SEE THE COST BEFORE YOU COMMIT Press and hold any group. You'll see what it scores and, more usefully, how many tiles it would strand. The obvious move and the right move are often not the same one. WIN, THEN PUSH FOR PERFECT Clear down to the round's goal and the win is banked — it can't be taken away. Everything after that is for stars. Leave a handful for two stars. Sweep the board completely for three and a bonus booster. EVERY BOARD IS BEATABLE A solver plays each board before you ever see it, and the round's goal is set from what it managed. You're never handed something impossible — and never handed something free. As you progress, the margin between the solver's line and yours narrows until you have to play nearly perfectly. WHEN YOU GET STUCK Undo takes back your last move, stranded tiles and all. Shuffle rearranges everything still on the board. Colour Blast clears an entire colour wherever it's stranded. Run out of moves and you'll be offered a way back in rather than a dead end. A NEW BOARD EVERY DAY The daily challenge hands everyone the same tiles. Build a streak, compare your sweep on Game Center leaderboards, and chase the achievements. BUILT PROPERLY • Full dark mode • Dynamic Type — the whole interface scales with your text size • Shapes on tiles for colour blind players, as a normal setting rather than something buried • VoiceOver labels on every tile, including what a move would strand • No timers. No lives. No waiting to play. MatchMint includes optional coin packs for players who want more boosters. You never need them to finish a level — every board can be cleared on its own terms.

Skyscrapers — A Mathematical Logic Puzzle Skyscrapers is a deterministic logic puzzle based on the mathematical concept of Latin squares, enhanced with edge visibility constraints derived from combinatorial optimization. Game Mechanics: • Grid Size: N×N (4×4, 5×5, or 6×6) • Domain: Fill each cell with integers 1 through N • Constraint 1: Latin Square — each integer appears exactly once per row and column • Constraint 2: Visibility Clues — edge numbers indicate count of visible buildings from that direction • Visibility Function: f(sequence) = count of elements where value[i] > max(value[0..i-1]) Difficulty Architecture: • Easy (4×4): Clue retention rate ~80%. Optimal for learning constraint propagation techniques. • Medium (5×5): Clue retention rate ~60%. Balanced complexity requiring multi-step logical deduction. • Hard (6×6): Clue retention rate ~40%. Advanced difficulty demanding systematic elimination strategies. Analytical Features: • Performance Tracking: Best completion time recorded per difficulty tier • Game Count: Total solved puzzles tracked per difficulty level • Auto-Save System: State persistence via UserDefaults with 500ms debounce • Undo Stack: Up to 100 reversible operations • Notes System: Candidate digit annotation for hypothesis testing • Conflict Detection: Real-time row/column duplicate and clue violation highlighting Technical Specifications: • Platform: iOS 16+ (iPhone, portrait orientation only) • Framework: Pure SwiftUI, zero third-party dependencies • Architecture: MVVM pattern with reactive state management • Performance: O(N) visibility calculation, deterministic puzzle generation • Privacy: 100% offline. No network access, no analytics, no data collection. Target Audience: Engineers, mathematicians, data scientists, and analytical thinkers who appreciate deterministic puzzles with no randomness in solution paths. If you value Sudoku, nonograms, or constraint satisfaction problems, this app delivers rigorous logical challenges.
