How to Play

1

Othello, Unchanged

Trap enemy discs between two of yours and everything in between turns. The rules are exactly Othello - what changes is the squares.

2

Squares Grant Weapons

Some squares give a sword, some a shield. Flip a disc and the weapon beneath it changes hands too, so "how many you flip" gains a second question: which ones.

3

Swords Attack, Shields Defend

Land on a battle square and two knights clash. The duel is decided by the attacker's swords against the defender's shields - you can hold more swords than your opponent and still lose to their shields. On a tie, the shield wins.

4

Ten Seconds a Turn

Fail to move within ten seconds and the turn passes. The Hourglass adds ten more; the Scout writes the outcome on every legal square - items only do the counting for you, they never change the result.

Four Knights, and What Lies on the Board

Three commanders hold three stages each, so across the nine-stage ladder you never meet the same face twice. Five things grow harder: how many moves ahead he reads, whether the board is 6x6 or 8x8, how many battle squares there are, how many weapons a single square grants, and how exactly he solves the ending. All five say "the opponent is stronger", but each is countered differently. When the armour colour changes, so do the discs he plays - red for the Squire, steel for the Lancer, moss green for the Axe Knight.

BLUE KNIGHT
BLUE KNIGHT
YOU

This is you. The board is yours as far as the blue discs reach.

SQUIRE
SQUIRE
STAGE 1-3

Sword and shield. He reads nothing ahead and simply grabs the most discs - in Othello that is the first mistake every beginner makes. The board is 6x6 with only two battle squares.

LANCER
LANCER
STAGE 4-6

Grey steel armour. He reads two or three moves ahead, the board grows to 8x8, and battle squares rise from four to six. From here a single square starts granting two swords or two shields.

AXE KNIGHT
AXE KNIGHT
STAGE 7-9

Mossy green armour. When few squares remain he solves the ending exactly - over the last ten moves he never errs. Eight battle squares, and one square can grant as many as three.

What Lies on the Board

Swords and shields are not a resource you bank - they are the running total of the squares your discs currently sit on. Flip a disc and the weapon beneath it changes hands, so one move can swing the numbers hard, and that swing is the tension of the game. The layout differs every match but is rotationally symmetric, so both sides start on exactly equal terms. H Coins come from the bonus round and the daily missions, and buy the items.
