8! Challenge vs Vector

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 8!
