NumShift!
Read full descriptionHide full description
Slide. Sum. Score. NumShift is a fresh take on the number puzzle. Slide entire rows and columns across a 5Ć5 board ā when adjacent tiles add up to the target sum, they merge and you score. Start simple with pairs that equal 10, then level up as the target climbs to 15, 20, and beyond. What begins as easy arithmetic becomes a strategic challenge as you plan moves ahead, set up chain reactions, and keep the board from filling up. WHAT MAKES NUMSHIFT DIFFERENT Unlike other number puzzles, you shift entire rows or columns ā not every tile at once. This gives you precise control over the board. And tiles don't merge by matching ā they merge by summing to a target. That one twist changes everything. HOW TO PLAY ⢠Swipe left or right to slide a row ⢠Swipe up or down to slide a column ⢠Adjacent tiles that add up to the target number merge automatically ⢠New tiles spawn after every move ⢠The game ends when the board fills with no possible merges FEATURES ⢠Unique target-sum mechanic ā not just another 2048 clone ⢠Open-ended levels ā targets climb 5 ā 10 ā 15 ā 20 ā 25 and beyond ⢠Combo multiplier system ā chain consecutive merges for massive scores ⢠Multi-tile merges ā combine 2, 3, 4, or even 5 tiles at once ⢠Undo button ā take back your last move ⢠Game Center leaderboards ā compete globally for high score and highest level ⢠More PapaG Games ā discover other PapaG titles from Settings ⢠Satisfying haptic feedback and sound effects ⢠Clean, minimal dark-mode design ⢠Works on iPhone and iPad ⢠No ads. No timers. No nonsense. Built by PapaG Studios ā a one-person indie studio making games worth your time.
