- One drag moves the whole board one cell — not as far as it can go. - Two equal numbers double only when the one in front has nowhere to go, so every merge is one you set up. - Nothing is random: the deck is written down, and the next three tiles are already on screen. - Four decks — plain numbers, stones to crack, a wild that takes any value, and a board that grows to 7x7. - A record kept per deck, seven colour themes, and the deck you played last remembered.
Stack the numbers up. Do not fill the board. Mouse and touch play the same: drag the board. Arrow keys and WASD work too. Z undoes. Escape or P pauses.
