8! Challenge: Dice Puzzle

Fill a 4x4 board with dice. Whenever a row or column adds up to exactly 8, it clears. That's the whole rule. Staying alive is the hard part.

Each turn you get a die (sometimes a double) and choose where to drop it. Every placement changes what the rows and columns add up to, so one careless move can lock the board up fast. Think a few steps ahead, set up chains, and keep cells open for whatever comes next.

HOW TO PLAY
• Drag the die from the stand onto any empty cell
• A row or column that totals 8 clears and scores
• Double dice take two cells at once, so place them with care
• The game ends when the board is full and nothing adds up

POWER-UPS
Running out of room? Spend the coins you earn from each game on three tools:
• Hammer: knock a single die off the board
• Bomb: clear a 3x3 area in one go
• Trash: throw away a die you don't want

WHY PEOPLE KEEP PLAYING
• Quick rounds that fit into a coffee break, or long runs when you're chasing a best score
• Simple arithmetic that still makes you think, a nice little workout for your brain
• One-handed play, no timer, no pressure
• Works offline, so it's good for commutes and flights
• A short tutorial gets you going in under a minute
