Lovely Runes
by Katie Splendor
Difficulty ●●○○
Lovely Whispers - Cages - Kropki
This lovely puzzle was inspired by “Companion Cube” and features killer cages in the exact same positions. The focus of the setter was fitting as many lovely whispers in as possible, and they definitely succeeded.
Orbital Sandwich

Difficulty ●●○○
Orbital Whispers - Sandwich Sums - Kropki
I was impressed by the amount of orbital whisper cells, and using the constraint in combination with the sandwich sums is a great idea!

Minchen’s Puzzle is a tribute to the upcoming Pokémon TCG set “Surging Sparks”. The octagon in the middle represents the Pokémon Terapagos, and the 18s in the cages are for the 18 different Pokémon types.

Sujoyku’s beautifully symmetric puzzle has some great interactions between different constraints!

Difficulty ●●○○
Region Sum Screws - Modular Lines
Gene made this wonderful puzzle with my region sum screw constraint, and putting these screws on a different type of line constraint is actually a great idea!
Moons
by Strosahl
Difficulty ●●○○
Quads - Kropki
Negative constraints can be quite painful to scan for. This puzzle by Strosahl uses them really well and limits their effect to certain areas, which makes the solve a lot more intuitive and fun!
Written On The Wall
by Bearly
Difficulty ●○○○
Counting Cages - X
This is Bearly’s first puzzle and also what inspired “Count to Ten”. The other constraints don’t give away much information, so the new counting cages constraint really is the focal point here.
The Arrow and the Whispers Should Be Friends
by ChinStrap
Difficulty ●●○○
Arrows - Dutch Whispers - Kropki
Featuring a great break-in followed up by a very smooth solve path, this puzzle by ChinStrap was a lot of fun to solve! At the time of playing this I had tried to make a puzzle with whispers and arrows multiple times and just ended up scrapping them every time, so this was a delight to see.
Dots and Quads
by Jobo
Difficulty ●●○○
Kropki - Quads
A really elegant puzzle set by Jobo. It looks appealing and almost seems like it shouldn’t solve, but it does. I love the amazing and unique use of the Kropki constraint here.
Astraea
by Minchen
Difficulty ●●●○
Renban Lines - Cages - Kropki
This is Minchen’s first puzzle, themed to the sword Astraea. It’s a lot of fun, and a great introduction to the Renban lines constraint.

Region Sum Lines - Cages - Little Killers - Jigsaw
This puzzle by aqjhs uses some beautiful logic, and the inclusion of zeros and negative numbers makes you think about sums in a completely different way!

Renban Lines - X/V Pairs - Kropki
One of the first puzzles I played on the CTC Discord server was this well themed and beginner friendly sudoku by waso suno. According to them this was their first puzzle, which is really impressive!

Difficulty ●●●○
Multi - Kropki
This idea was sparked by their previous puzzle “Little Brother”. This puzzle is incredibly unique and creative, but definitely a step up in difficulty from the previous one.
Little Brother
by Michael Lefkowitz
Difficulty ●○○○
Multi - Kropki
I’ve always loved multi sudoku, even before I’ve started playing variants. This puzzle by Michael Lefkowitz was surprisingly clever, since it uses 2 grids with different sizes. That alone is already pretty constraining and leads to a unique solution with only a few additional Kropki dots.
Hedge Maze
by Jobo
Difficulty ●●●○
German Whispers - Kropki
Jobo surprised me with a really creative use of the German whispers constraint in this puzzle. The theme also works really well and we’ll hope that the little guy eventually makes it through this maze.
Equilibrium
by SneakySteve
Difficulty ●●○○
Hot/Cold Arrows - X
This beautiful puzzle was made by SneakySteve for a monthly sudoku creating competition with the theme “Balance”. It’s not only visually appealing, but also plays really well and I with the chemistry-related name I just had to feature this puzzle.
