— HOW TO PLAY —
RULES & CONTROLS
Mini chess on a 4×5 board. Same rules as standard chess — just smaller and faster.
PIECES
♚ ♔ King — moves one square any direction. Protect it.
♛ ♕ Queen — moves any direction, any distance.
♜ ♖ Rook — moves horizontally or vertically.
♟ ♙ Pawn — moves forward one square, captures diagonally. Promotes on the last rank.
CONTROLS
Click a piece to select it, then click a highlighted square to move.
Legal moves show as dots. Captures show as a pink ring.
Win by checkmating the bot's king.
DIFFICULTY
RND Bot moves randomly.
EASY Bot looks one move ahead.
MED Bot thinks 3 moves deep.
HARD Bot plays near-perfectly.
Standard sudoku rules — but the 3×3 boxes are replaced with irregular jigsaw-shaped regions.
OBJECTIVE
Fill every cell so that each row, column, and colored region contains the digits 1–9 exactly once.
No repeats in any row, column, or region.
CONTROLS
Click a cell to select it, then click a number on the pad (or press 1–9 on keyboard).
✎ NOTES Toggle note mode to pencil in candidates.
↩ UNDO Undo your last move. Ctrl+Z also works.
Arrow keys navigate between cells.
SCORING
Score is based on difficulty ceiling (Easy 500 · Med 1500 · Hard 2500).
Efficiency = 60% mistakes (0 = perfect) + 40% time remaining on the clock.
You have 5 minutes. The clock shrinks by 5 seconds every time you win.
Win streak multiplier: ×1 → ×1.2 → ×1.5 → ×2 for 4+ consecutive wins.
Every new game is a unique puzzle — different solution, different regions, different givens.
Stack falling pieces, clear lines, survive as long as possible. Includes 2 custom pieces beyond the classic 7.
CONTROLS
← → Move piece left / right.
↑ Rotate piece clockwise.
↓ Soft drop — fall faster.
SPACE Hard drop — instant place.
SHIFT Flip piece horizontally.
R Restart after game over.
SCORING
1 line = 100 pts · 2 lines = 300 · 3 lines = 500 · 4 lines = 800.
Combo multiplier stacks with consecutive clears.
Speed increases at score milestones — board gets faster and angrier.
SPECIAL
Ghost piece shows where your block will land.
Garbage rows start appearing at level 3.
There's a secret easter egg at 6,700 points. 👀
9 tic-tac-toe boards arranged in a 3×3 meta-grid. Win local boards to claim meta cells. Win 3 meta cells in a row to win the game.
HOW IT WORKS
Each move sends your opponent to a specific local board — the board matching the cell position you just played.
Win a local board → that meta cell is yours.
If the target board is already won or full, your opponent can play anywhere.
Win 3 meta cells in a row to win the whole game.
STRATEGY
Think two levels at once — local tactics AND where you're sending the bot next.
Avoid sending the bot to the center board (#5) — it's the most valuable.
Winning the center meta cell gives you the most winning lines.
The "NEXT BOARD" indicator shows where you must play.
DIFFICULTY
EASY Bot plays randomly. Good for learning the rules.
MED Bot wins/blocks locally and thinks about meta strategy.
HARD Bot uses minimax at depth 5 across both levels. Very tough.
Score ceiling: Easy 500 · Med 1500 · Hard 2500. Fewer moves = higher efficiency. Win streak multiplier up to ×2.
