Placement Platter #1

      Tetrochain, Tren, RGB Akari, W.Briquet and Hebi-Ichigo : finally, we are serving a batch of Object Placement puzzles. These are the most diverse in shapes and rulesets, and may need to be studied before attempting big puzzles. Only Hebi-Ichigo is tougher than what I can recommend for beginners, and Iwa Daigeki has plenty of smaller, easier ones if you don't want to leave this one out. Tetrochain CBT is a twist I like with Tetrochain, you can check the puzzles I've made with the tags on the right. I promise posts focusing on one type will return.

     Thanks to Wisteria for testing the RGB Akari, and Wessel for testing the Wittgen, the Tetrochain, and attempting the Hebi.

RGB Akari 🔴💡🟢💡🔵

     Yesterday, we took a glance at Akari puzzles. While the genre is fun to solve at all levels, it's still fairly restricted in terms of inputs (as you only place lightsbulbs in some cells), compared to types like Sudoku or Hakkyu (with numbers). Here is a very recent way to dirversify the solving of Akari : RGB Akari ! Created a week ago by Jubale & Jolson, here are the rules :

Place red, green and blue lightbulbs in some cells of the grid.

- Lightbulbs illuminate cells in the same row and column it's in, stopping at the edge of the grid or a black cell.

- Every white cell is illuminated by at least one lightbulb.

- No two lightbulbs illuminate each other.

- Numbers in black cells represent the numbers of lightbulbs in the 4 adjacent cells.

- Colored tiles must be illuminated with the corresponding light color(s). Lightbulbs may be placed over tiles.
