HOW TO PLAY

• The board is a pyramid. Some tiles are already filled; the empty ones are yours.
• Tap a tile, then tap a number (or use your keyboard). Each round allows certain numbers (shown up top).
• Row totals: the gold tile at the end of each row is that row's total. It counts one half of the row plus the shared middle tile — and both sides must add up to it. So the left and right sides always match. A correct row turns green.
• Column totals: the number under each column is its total — every column must add up to its number too. These link the rows together.
• Some totals are hidden as ? on harder rounds — work them out from the rest; they appear once you solve that line.
• Fill every row and every column to their totals to clear the round.
• Stuck? Spend a 🧭 Assist — it finds the next solvable tile, shows you the reasoning, and fills it in. You get a limited number each round, so save them for when you're truly stuck.
