CrossSum - Number Merge Puzzle

Don't swipe. Tap. CrossSum isn't a puzzle you push around the screen. Tap a single tile and every matching number above, below, left and right of it comes rushing in at once and merges where you tapped. A row and a column meeting at one point and adding up - that's the Cross Sum. The rule fits in one sentence. Which tile you tap first changes the whole board. [ Hundreds of stages ] Every stage asks for something different. · Build a specific number · Set off a set number of combos · Finish within a limited number of moves · Finish before the clock runs out · Pass a target score · Leave an exact number of tiles on the board Mix in boards with blocked cells and open holes, and the same rule keeps solving differently. Clear one stage to open the next. [ A new challenge every day ] The Daily Challenge gives everyone the same board each day. The biggest number you make earns a bronze, silver, gold or diamond medal, and a month of medals builds up to a monthly trophy. Earlier days of the current month can be replayed from the calendar. In Rank Mode you spend a key to climb the leaderboard. Pick a name and flag, and that is what everyone sees. [ Items for when you're stuck ] · Undo - take back the move you just made · Hammer - smash one tile that's in your way · Magic Wand - double the number on a tile Three of each per run, no more. These aren't a way to steamroll the board; they're for the one moment you really don't want to lose. [ Something to collect ] New tile designs unlock as your scores, stages and daily record build up. A global leaderboard shows where everyone else has landed. [ Also worth knowing ] · Start as a guest and link a Google account later - your progress comes with you · Free to play with ads.
