About Survey Grid
Survey Grid is a placing game for one. A shuffled pack deals you nine cards, one at a time, and each one must go on an empty square of a three-by-three grid before you see the next. When the grid is full, the eight lines through it, three rows, three columns and two diagonals, are each read as a three-card hand.
The centre square sits on four lines, the corners on three and the edges on two, so where a card goes matters as much as what it is. A pair placed on a corner and the centre can feed a row, a column and a diagonal at the same time. A card that fits nowhere is best parked where it spoils the fewest lines.
The hands are simple: a pair, three of one suit, three in a run, three of a kind, or a run in one suit. Each line scores points and the round returns a multiple of your stake from the points total. If you want a second opinion, Suggest a square marks the square our helper would pick, and Finish for me places the rest of the cards the same way.
Field key: how to play
- Pick a stake: 10, 25, 50, 100 or 250 ink, then press Deal.
- The card in hand goes on any empty square. Then the next card is turned.
- When all nine squares are full, each of the eight lines (rows, columns, diagonals) scores: pair 1, three of one suit 2, run 3, three of a kind 6, run in one suit 8. Ace counts high or low in a run (A-2-3 and Q-K-A both count).
- The total of the eight lines sets the return from the key below, as a multiple of your stake.
- Suggest a square marks a sensible square for the card in hand. Finish for me places every remaining card with the same advice.
Returns
Every return is a multiple of what you staked. Ink has no cash value and nothing on Carthoryn can be exchanged for anything.

Questions
Is the helper the best possible play?
It is a good, simple rule of thumb: it favours squares that keep the most lines promising. A careful player can sometimes do better, and a hasty one will often do worse.
What happens if I leave mid-grid?
The round is lost with the stake already placed. Use Finish for me if you need to go.
Does the pack remember previous rounds?
No. Every round shuffles a full pack of 52 cards from scratch.
