About Tenfold (Puzzle Round)
Tenfold is a make-ten puzzle with gravity. The board is a 5x5 grid of 25 number tiles, the same for everyone each day, and the goal is to clear every one of them, which takes ten clears.
You select a connected group of two or three tiles that share edges and whose numbers add up to exactly ten, then press Build a ten. The tiles above the cleared group fall straight down, which brings new numbers next to each other and opens new combinations. If no group of ten is left before the board is empty, the Undo button takes back your last clear so you can try another order.
It plays like a short puzzle version of make-ten mobile games, with one fixed board and a solve time on the daily leaderboard instead of an endless stream.
Puzzle Round is a free website of short daily puzzles by thatsoftwaredude, an independent developer. Every player gets the same puzzles each day, a countdown on the site runs to the next midnight UTC, and each game keeps its own daily leaderboard ranked by solve time. You can play without signing up; a free account saves your result to the leaderboard and keeps your streak, and private Circles let a family or a group of friends compare results. Clearing the whole lineup in a day counts as a Perfect Day.
