primoz: Prime Number Puzzle

Prime numbers fall: 2, 3, 5 and 7. Place them so rows or columns total 10, 20, 30… to clear blocks and reach each round’s point target before the rising floor pushes the stack to the top.

Swipe to guide each falling block. Make space with a simple sum or plan a placement that clears a row and a column at once. You don’t need to fill a whole row: the numbers just need to add up. Clear several lines together for extra points. The remaining blocks fall into place and can trigger a chain reaction.

The challenge comes from both directions. Prime numbers keep falling from above, while fresh rows push the stack up from below. Completing a round clears the board and gives you room to start again, with a higher point target to work towards.

Choose Easy, Normal or Hard to change how quickly the blocks fall and how often the floor rises. The totals beside the board help you spot your next clear. A downward swipe speeds up a block when you know where you want it.

Features:
• Four prime numbers, with new combinations on every board.
• Bonuses for consecutive clears, clearing several lines at once and an empty board.
• Separate best scores and highest rounds for each difficulty.

Keep the sums coming and see how many rounds you can reach.
