Fibonacci: Sudoku & Merge

Fibonacci Sudoku: Five Number Puzzles in One

Dive into the beauty of the Fibonacci sequence with two original number games, then sharpen your logic with three kinds of Sudoku. Sign-in optional – just puzzles.

FIBONACCI MERGE
Slide the 8x5 grid and merge neighbouring Fibonacci numbers into the next one: 1+1=2, 1+2=3, 2+3=5, 3+5=8 and beyond.
• Classic mode: reach 89, then unlock bigger targets all the way to 6765
• Time Challenge: reach 55 within 5 minutes
• Special tiles: coin tiles pay out when merged, frozen tiles stay put for a while, obstacles reshape the board
• Power-ups: Clear Row and Unfreeze when you get stuck

FIBONACCI LINK
Drag across neighbouring tiles to link a run of the sequence, like 1-1-2-3 or 2-3-5-8.
• Chain valid links back to back for a growing combo multiplier
• Link 8, 13 and 21 to trigger Golden Mode and double every point on the board
• Endless levels with rising score targets
• Power-ups: Lock, Shuffle and Remove Row

SUDOKU – CLASSIC, KILLER AND JIGSAW
• Classic: the timeless 9x9 puzzle
• Killer: cages with sums instead of given numbers
• Jigsaw: irregular regions instead of 3x3 boxes
