On the 7x7 board, each player starts with 41 light pawns and only 15 dark ones. That imbalance is no accident, and understanding it is probably the single best way to stop losing.
The dark pawn is not expensive, it is rare
Yes, a dark pawn is worth 2 points against 1 for a light one. But if it were only a matter of value, you would get the same number of each. The real role of the dark pawn lies elsewhere: it is the only pawn that validates a cube.
The rule again: a closed square only counts if each of its four corners is held by at least one dark pawn. You can surround a square with four magnificent light pawns and it will be worth nothing. Your 41 light pawns score no points at all without your 15 dark ones.
A well-placed dark pawn works for four cubes
A dark pawn overhangs into the corners. A crossing on the board touches up to four squares. So a single dark pawn, placed at the right spot, can validate a corner in several cubes at once and add 2 points to each of them.
That is where the game is won. A beginner places dark pawns where they close something right now. An experienced player places them where they will do the job three times.
Why a cube is worth 6, 9 or 12
The count is simple once you have seen it:
- Add up the four sides: 1 per light pawn, 2 per dark pawn.
- Add 2 points for every dark pawn outside the cube that overhangs into one of its corners.
A cube held by two light and two dark pawns is worth 6. The same cube with one more dark pawn pointing into a corner from outside is worth 8. With three dark pawns on the sides and an outside reinforcement, you reach 9. And a complete 2x2 square, eight pawns alternating, is worth 12 in one shot.
Two players can therefore close the same number of cubes and finish miles apart. It is not how many cubes you close, it is how dense they are in dark pawns.
The end-of-game punishment
Here is what turns the most games around. When play ends, every pawn still in your hands is subtracted from your score: 1 point per unplayed light pawn, 2 points per unplayed dark pawn.
Fifteen dark pawns kept in hand is thirty points gone. Many beginners finish a game with a positive cube score and a deeply negative net total, simply because they were thrifty.
In the app, touch a player's card during the game and you will see their estimated net, meaning what their score would be worth if play stopped right now. That is the number to watch, not the raw points.
Three habits to build
- Spend your dark pawns. A dark pawn in hand is worth minus two. A dark pawn on the board is worth two and earns more.
- Place dark pawns at shared crossings, where four squares meet, rather than along an edge.
- Count before you close. Closing a 6-point cube that hands your opponent a 12-point one is not a good deal.
