## What is Fuse 6×6?

A simple puzzle where you swipe to merge numbers on a 6x6 board.
It keeps the feel of the original, and eight kinds of panels drop onto the board to make every run different.

= Eight panels that drop onto the board
- x2 / x4 - once charged, doubles or quadruples a number with no partner needed
- Magnet - pulls every matching number across the board and steps each one up
- Up - raises the four neighboring numbers one step, then disappears
- Bomb - explodes in a cross of 5 cells. Iron is destroyed, numbers drop four steps
- Sweep - clears every 2 on the board. The longer it charges, the more room it opens
- Iron - a blocker that never merges. It moves only one cell per turn, and only a bomb removes it
- Wood - a lighter blocker. Move it three times and it breaks on its own

Helpful panels do not merge while they are charging. That gives you time to arrange the board and aim them at the number you actually want, so you never spend one by accident.

= Breaking iron is what keeps you alive
Iron is a blocker only bombs can remove, but every one you break pays you back.
- Every 10 you break earns an extra life (up to 5)
- Spending a life clears up to 18 tiles of 64 or less, smallest first, so you can keep going
- Each break has a 30% chance to shield your largest number, absorbing one blast

The more you have built up, the harder it is to lose.

= Global leaderboards (opt-in)
Compete on score, moves, and iron destroyed. Taking part is your choice, and only the final numbers are sent.

= Also
- No connection needed to play (only the leaderboards go online)
- Stop anytime and pick up where you left off
- No ads
- Free to play. When you are truly stuck, you can buy three continues (one-time purchase, optional)

Numbers stay exact all the way to 2^1023. See how far you get.
