Royals7

Number-building grid game

Royals7 is a PC strategy game built around making arithmetic expressions to claim spaces on a grid. You’re trying to line up four claimed cells across, down, or diagonally. Each cell has a target number, and you make it by spending cards from a five-card hand, using up to three cards and any of six operations.

The board evaluates expressions strictly from left to right, without standard order of operations. So 2 + 3 × 4 makes 20, not 14. Concatenation joins digits, exponentiation raises one card’s value to a power, and multiplication, exact division, addition, and subtraction are also available. An expression can go negative partway through. For example, a target of 96 can be made by joining 9 and 6; a target of 30 can be made with 5 × 6 or 2 + 4 + 6.
