A clear boundary between the official 300-level claim and the level-specific details that are not publicly verified.
That is the level-count statement on the official Roblox description. The description does not provide a campaign map, level order, solutions, unlock rules, or difficulty curve, so this guide focuses on a reliable puzzle-review routine.
The public description says each row, column, and colour region should contain one Chiikawa. It also names a personal-best streak and an unlimited random challenge mode. It does not say which level introduces a rule or what a particular board requires, so inspect the current board for the answer.
Identify the row, column, and region that constrain your next placement.
Do not treat another level's layout as a solution for the board in front of you.
Use the endless-mode page for the unlimited random challenge instead of assuming its rules are campaign progress.
The official Chiidoku description says the game has up to 300 levels.
No verified public level-by-level solution list is available here. Use the puzzle-rule guide and the in-game board rather than assuming a fixed walkthrough.
The official description separately names an unlimited random challenge mode. It does not explain how that mode is connected to level progress.
