i built this out of love for 2048. that game is endlessly satisfying — the merging, the strategy, the one-more-go loop. but i always wanted something more from it.
my thing is games that leave you knowing something you didn't before. not a lecture — just a fact that sticks. you merge two rivers and suddenly you know the Amazon is longer than the Mississippi. you didn't study it. it just happened.
f1bonacci is that idea. same gameplay, real sequences, random facts that actually land. more themes coming.
f1bonacci is a living game. some sequences are clear — rivers have lengths, mountains have heights. others involve real choices: which 11 items define a theme? where exactly should item 4 sit relative to 3 and 5? these decisions are debatable, and your perspective matters.
suggest a new theme
got a topic you'd love to see? drop it on reddit with a few items you'd include and why — the best ideas come from people who care about a subject.
challenge a sequence
think an item is in the wrong position, missing entirely, or shouldn't be there at all? make the case. good arguments with sources get taken seriously.
bugs & feedback
something broke? a layout looks off on your device? a fact tile has a typo? report it and it gets fixed. design and gameplay feedback also very welcome.
know someone who'd enjoy this? send them the link — the best way for f1bonacci to grow is word of mouth from people who like it.
how to play
slide in any direction — up, down, left or right — in order to merge the same tiles into new ones to progress with the sequence.

swipe or press arrow keys
all tiles slide as far as they can in that direction. every move spawns a new tile.
🔗
identical tiles merge
when two of the same tile collide, they combine into the next item in the sequence. each pair merges only once per move.
📋
tap a tile to read its fact
every tile has a short fact about what it represents. it's the whole point.
🏁
reach tile 11 to win
each theme has 11 items in sequence. build up to the final tile to complete it. the board fills and the game ends if no moves remain.
