Bridges joined Ponder on 11 October and appeared in the Daily set from the next day. Within a couple of days, players were telling us the same thing: the Challenging Bridges stage was too hard to race. Since 14 October, Daily Bridges boards are Standard instead. Here’s why, and what we left alone.
What players told us
The complaint wasn’t that Bridges is a bad puzzle. People liked it in the Library. The trouble was the Race. When one stage takes far longer than the other five, it decides the result on its own. Whoever happened to see the key connection first won, and everyone else spent the rest of their run staring at islands. A race that turns on a single board isn’t much of a race.
Why Challenging Bridges is slow in a hurry
Ponder grades each Bridges board by its size and by the hardest reasoning it needs. Gentle boards have 7 islands and can be solved from the island numbers alone. Standard boards have 11, and also ask you to notice crossings and connections that one group of islands needs to reach the rest. Challenging boards have 15 islands, and the hardest of them ask for one more kind of step: suppose a connection, follow it until something breaks, then take it back.
That last step is what makes a Challenging board satisfying on a quiet afternoon. It’s also where a racer gets stuck, because nothing on the board tells you which connection to try. Every other family in the Daily set has a hard step too, but Bridges adds a second trap. A mistake that cuts off part of the network can be easy to miss until late in the board.
What changed
From 14 October, the Daily set uses Standard Bridges boards with 11 islands. Mini Sudoku was already Standard in the Daily set; the other six families stay Challenging. The set still has six puzzles from six of the eight families, and never the same six as the day before.
Daily boards come from a private reserve that never appears in the Library, so we made 60 new Standard Bridges boards for it, each checked for a single solution like every other board. Daily sets are prepared a few days ahead. The sets for 14 to 17 October hadn’t opened yet, so we rebuilt them with the new mix.
What didn’t change
A Daily set never changes once it has opened. Sets that had already opened keep their Challenging Bridges boards, and every result from those days stands as it was. If you raced one of them, your time is still comparable with everyone else who raced that day.
Challenging Bridges hasn’t gone anywhere, either. The Library has a hundred Challenging boards, and every Weekly collection includes two of them. If you enjoyed the hard ones, that’s where to find them. The Bridges guide explains the rules and a first move if you’re new to it.
A label is a guess until people play
Our grading is a useful starting point. It tells us how much reasoning a board needs, and it never lets through a board that needs guessing. What it can’t tell us is how long a stage feels with a clock running and a friend’s time to beat. Players found that out in two days.
We’ll keep watching the other stages the same way. If one feels out of line, in either direction, please tell us. The more specific you can be, the better: which day, which family, and where you got stuck. For more on how families earn their place, see how we choose Ponder’s puzzles.
