What was the Summer Special?
A special version of the app was released in summer 2021, containing an extra set of unusual and entertaining puzzles for players to enjoy during the summer holiday season. Some graphical adaptions gave the app a distinctive summer look and a new leaderboard was added, dedicated to the special puzzle set.
When was the Summer Special available?
The Summer Special went live in the App Store on the day of the summer solstice, 21st Jun 2021. It has now been superseded by version 1.12, which is a return to the normal look. However, the extra set of puzzles is still included in this latest version and can be played until the end of August.
Where can I find the special set of puzzles?
On the page for Puzzle Sets - just tap the butterfly symbol.
If the butterfly symbol is not showing then it may be because you have an old version of the app (the latest is 1.12, tap the info icon below the main menu to check), or because the special set is no longer active (see the paragraph on dates, above).

What is so special about the puzzles?
The extra set of puzzles has three groups of puzzles:
From 3x3 to 9x9
Every possible size of puzzle, from the smallest to the largest. The 9x9 is one of only a few rare examples of this size of puzzle!
| # | Size | Difficulty | Logical complexity |
|---|---|---|---|
| 1 | 3x3 | Easy | Normal |
| 2 | 4x4 | Easy | Normal |
| 3 | 5x5 | Medium | Advanced |
| 4 | 6x6 | Quite easy | Normal |
| 5 | 7x7 | Quite easy | Normal |
| 6 | 8x8 | Difficult | Normal |
| 7 | 9x9 | Very difficult | Normal |
Sum symmetry
With these puzzles, the rows and the columns have exactly the same sum values, so the solved puzzles are also symmetric across the diagonal. This can make it a little easier to solve the puzzles, because you only need to solve half a puzzle to solve it all! However, they are not all as easy as they might at first seem.
| # | Size | Difficulty | Logical complexity |
|---|---|---|---|
| 8 | 5x5 | Quite easy | Normal |
| 9 | 7x7 | Quite easy | Normal |
| 10 | 6x6 | Quite easy | Normal |
| 11 | 5x5 | Medium | Expert |
| 12 | 6x6 | Difficult | Expert |
| 13 | 5x5 | Difficult | Expert |
| 14 | 7x7 | Medium | Normal |
| 15 | 6x6 | Very difficult | Expert |
Turn up the logic
These puzzles may be small, but they are especially tricky! They showcase the additional logical complexity that can be turned on with the Random Play puzzle generator.
| # | Size | Difficulty | Logical complexity |
|---|---|---|---|
| 16 | 5x5 | Difficult | Expert |
| 17 | 6x6 | Very difficult | Advanced |
| 18 | 6x6 | Difficult | Expert |
| 19 | 5x5 | Very difficult | Expert |
