Start Chiidoku in Campaign and use the early puzzles to build one habit: never place a Chiikawa until the row, column, color area, and neighbor condition all agree. The official description says Campaign now reaches level 400, but your first goal is not speed or completion. It is learning to explain why a cell is legal before touching it.
Before your first puzzle
Join from the official Roblox page and confirm the creator is 미지 스튜디오. This avoids copied experiences and outdated descriptions. Read the current English game description: one Chiikawa belongs in each row, each column, and each color area, and Chiikawas cannot be placed next to each other.
The public wording does not define whether “next to” covers only shared edges or also diagonals. Inspect the current tutorial, placement highlighting, and error feedback. Treat that live behavior as the device-specific answer until the creator publishes a precise direction rule.
Use a four-check placement routine
After every placement, restart the four checks. One Chiikawa closes several possibilities at once, so the board can reveal a new forced cell immediately. A fixed rescan is safer than continuing from the color that last caught your eye.
Complete the first session in stages
First, clear a few early Campaign puzzles without guessing. Pause before every tap and name the constraint that forced it. Second, open the current mission panel and note what it actually asks; daily objectives and rewards are not published in detail. Third, look at the character collection only after you understand how the displayed coins are earned and spent.
Leave Endless Mode until the row-column-color scan feels automatic. The creator says Endless uses randomly generated puzzles, has no level limit, and becomes more challenging. That makes it an endurance test, not the best place to learn a rule you are still misreading.

Use it for: learning constraints and making steady numbered progress.
Not public: exact difficulty bands, rewards, solutions, or unlock gates.
Endless Mode
Confirmed: random puzzles with no level limit and rising challenge.
Use it for: testing consistency after Campaign basics.
Not public: entry conditions, failure rules, reward formula, or curve.
Daily missions
Confirmed: refresh every day and provide rewards.
Use them for: a short current-session objective.
Not public: task list, reset hour, progress rules, or reward amounts.
Collection
Confirmed: playing earns coins used to unlock characters.
Use it for: choosing collection goals after learning the grid.
Not public: full roster, costs, rarity, or gameplay effects.
Recover when a board stalls
Do not tap the most attractive cell. Recount open rows, columns, and color areas, then apply the adjacency behavior demonstrated by your current game. Look for a unit with only one remaining legal candidate. If none appears, compare how two constrained areas compete for the same rows or columns and continue eliminating without committing.
If your notes become confusing, clear the mental candidate list and rescan from the current placed tokens. On a small screen, verify that you are looking at the intended color boundary. If you cannot explain a placement in one sentence, wait. The detailed solving strategy gives a fuller recovery loop.
Avoid costly beginner mistakes
Old pages may say the campaign stops at 300 or that adjacent Chiikawas are allowed. Both conflict with the current English official description and August update event. Use 400 and the current no-adjacency wording, while leaving the exact direction scope to live testing.
Do not assume characters provide power, that daily missions always grant coins, or that every Campaign or Endless action pays the same amount. Those details are not established publicly. Read the interface before choosing a grind route.
Do not buy a pass to fix unclear logic. The catalog names Heart + 1 and 2x Rewards Pass, but its descriptions are blank. Learn why you fail and inspect the current in-game effect before spending Robux. Gamepasses separates catalog facts from untested behavior.
Pick the right next page
Use How to Play for the current rules, Adjacency Rule for the version conflict, and 400 Levels for a campaign plan that does not invent level answers. When you want rewards, open Daily Missions and Coins, then compare what those pages say with the live screens.
Frequently asked questions
Should I play Campaign or Endless first?
Campaign first. It begins with simpler puzzles and provides a numbered progression. Endless is random, uncapped, and designed to become harder.
What does a legal placement need?
It must satisfy the one-per-row, one-per-column, one-per-color-area, and current no-adjacency constraints. Confirm the directional meaning of adjacency in the live tutorial.
Are there 300 or 400 levels?
The current official description and update event say 400. The 300 figure is stale.
Do characters make puzzles easier?
The official description only confirms that coins unlock a variety of characters. It does not publish abilities or say they change puzzle rules, so do not assume a power benefit.
Do I need Robux to progress?
No public source says either current pass is required. Learn and test the free play loop before considering an optional purchase.
