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.
• Variations keep rounds fresh: limited number pools (evens, odds, primes…), 🪞 MIRROR (tiles equal their partner across the row), 🔢 NO REPEATS (long rows use all-different numbers), 🧱 LOAD-BEARING (every tile is bigger than the tile resting on it), and ✖ MULTIPLY! — rows and columns multiply to their targets instead of adding.
• Special rounds appear as you climb: ⬇ TILE DROP (numbers fall from above, Connect-4 style), ▲ 3D ROTATE (a three-sided pyramid you turn to find clues), ⏱ TIME ATTACK (beat the clock for a big bonus — no penalty if you don't), and ⚡ BONUS ROUNDS as you climb.
• Fill every row and every column to their totals to clear the round — the climb continues, getting tougher as you go.
• ❤️ Lives: every mode has a limited number of hearts — a wrong row, column, or entry costs one. You'll be warned as they run low; lose them all and the run ends (your score still counts). In the timed challenge the clock can beat you too.
• 🃏 The Joker (one per run, more from flawless ⚡ bonuses): place it on any tile and it becomes whatever its lines need once a total closes around it.
• 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. 🏳 Give Up reveals the solution but ends your run.
