Number Pyramid
Number Pyramid is a sums puzzle. Every block is the sum of the two blocks below it. Fill in the missing numbers on the pad before the clock runs out. Pyramids get taller and hide more blocks as you go.
How to play
- Look at the visible blocks and find one you can work out.
- Type the number on the pad. The next empty block is chosen for you.
- Solve the pyramid to add seconds and move up to the next one.
Tips
- Start from a block whose two supports are both known.
- Subtract to work downward: the top minus one side gives the other.
- A mistake costs two seconds and resets your clean streak.
