Best Sudoku App for Quick Games: Short Breaks, No Waiting

For a puzzle you can finish in a short break, pick an app with a small, easy level and a reliable save. nerByte Sudoku is the only app here whose listing has a level called "Fast", PeopleFun Sudoku sells itself on "a quick 5-minute break", and Tripledot, Stress Free Sudoku and Sudoku Now! all say a puzzle is saved when you leave. Sudoku Royale fits short sessions through Easy and Medium Practice, one Daily Challenge, and Dojo drills that are short and timed by design, and it has no ads to sit through between puzzles. The catch with most free apps is that the break is spent on ads, not on the puzzle. That is worth checking before you choose.

What makes a game quick

A short session depends on three things: a level small enough to finish, a save that holds when you get pulled away, and nothing between you and the next grid. The table shows what each app's listing says about those three.

Three short formats in Sudoku Royale

Sudoku Royale was not built around a stopwatch, but it has three ways to play that fit a coffee break or a wait at the doctor's.

• Easy and Medium Practice. Most Easy puzzles need nothing beyond naked singles and hidden singles, so they move fast once you know where to look. Practice has no countdown and no mistake limit, and if you leave a puzzle half done, it is saved and waits for you next time. The clock picks up from where it stopped. See how Practice works.
• One Daily Challenge. One puzzle, and you are done for the day. It keeps a streak, so a short daily session adds up to something. While the app is in the background the Daily clock stops counting, so a phone call does not cost you time. It needs a connection. More in the Daily Challenge guide.
• Dojo drills. The Dojo runs short, timed drills on a single technique: you spot the pattern again and again until it is quick. It is the most useful thing to do with a few spare minutes if you want your full-length solves to get faster. It also needs a connection.

Ads eat short sessions first

In a 45-minute session an ad between puzzles is a small cost. In a five-minute break it can be a large share of the time. Every competitor in the table either carries Apple's "Contains: Advertising" note in its age rating or sells a way to remove ads. PeopleFun's listing describes an optional ad-free subscription; nerByte and Sudoku Now! list a paid ad removal. Sudoku Royale has no ads and nothing to buy, so a quick game is just the game. If ads are the main thing you are trying to avoid, the best sudoku apps with no ads go through every option.

Getting through a puzzle faster

If you want shorter games without dropping to an easier level, the speed comes from input and pattern recognition more than from the app. A few habits help:

• Place numbers in runs. Pick a digit first and then tap every cell it goes in. In Sudoku Royale you can arm a number on the bar, or hold the key and fill cells with the other hand. Our number-first versus cell-first guide explains why this is faster.
• Scan before you write notes. On Easy and Medium, many cells fall to singles without any pencil marks.
• Drill the step where you stall. If you always slow down at the same point, it is usually one technique. A Dojo drill on it does more than another full puzzle. Our speed-solving guide has more.

Where another app is the better pick

• You want the smallest puzzle possible. nerByte Sudoku lists a "Fast" level ahead of Easy, and Stress Free Sudoku lists a large pool of "Very Easy" puzzles. Sudoku Royale's easiest level is Easy.
• You play quick games offline. Sudoku Royale's Daily Challenge and Dojo need a connection; only Practice puzzles already downloaded and the Journey play offline. The best offline sudoku apps cover apps that promise full offline play.
• You want undo. Sudoku Royale has none. Tripledot, Stress Free Sudoku and Sudoku Now! list undo.
• You play on Android. Sudoku Royale is iPhone and iPad only.

Our pick

If your breaks are short and you want all of them spent solving, try Sudoku Royale: Easy Practice for a fast grid, the Daily Challenge for a single puzzle with a streak, and a Dojo drill when you want to get quicker. If you need the very easiest grids or long stretches offline, nerByte Sudoku or Stress Free Sudoku match that better.
