System_X

⊞ NONOGRAM: the grid deduction game from before. Read the row/column clue numbers, fill the correct cells with pure logic. Errors cost time. Three difficulty tiers (5×5 → 7×7 → 9×9), 6 puzzles each.

⌁ CIPHER: a substitution cypher intercepted in the field. Every letter in the encoded message maps to a different letter. Type the plaintext for each character. Auto-fills duplicate encoded characters as you solve, so cracking one unlocks others. Use HINT sparingly; it costs 30 seconds. Harder difficulties use longer words.

∿ SEQUENCE: 10 questions per session, each a logic series with one missing term. Covers arithmetic, geometric, Fibonacci-style, squares, cubes, alternating operations, and second-order differences. Multiple choice, timed per question. You need 7/10 to score points.

◈ MEMORY: a pattern of cells flashes briefly. Then it vanishes. Reconstruct it exactly. Each round adds more lit cells. It never stops until you fail; your score is how deep you went.

Shared across all games: one global score, level, and streak counter. A win in any game feeds the streak multiplier that boosts every other game's bonus. A fail resets it.

Keyboard: 1-4 to switch games, D/F/N in Nonogram, Tab to advance fields in Cypher.
