Chiidoku's economy is small and documented: coins come from playing, coins unlock characters, and characters are cosmetic. What nobody has published is a price — so this page teaches you to plan the economy from your own measured numbers instead of invented ones.
Checked 2026-10-25. Each row names where the fact comes from.
Earned by playing: the official listing ties coins to level progression ('complete over 1,000 levels, earn coins'), and community wikis add campaign clears, daily missions, and endless streaks as sources. Coins are the game's only named currency.
GamerTweak's pre-rename guide says coins earned through gameplay unlock new characters of your choice. No character price has been published, and the October 2026 listing no longer mentions a character collection.
Both community wikis state the collection never changes the grid — characters do not alter difficulty, rules, or payouts. They are collectibles, not power upgrades.
Wrong placements consume hearts; run out and your progress on that attempt stops. Recorded zero-heart runs show the system biting in real play.
chiidokugame.wiki lists Heart + 1 at 149 Robux and a 2x Rewards Pass at 249 Robux, and notes neither pass solves boards for you.
A calculator needs inputs. Chiidoku's creator publishes none, so the honest inputs are the ones you can measure in-game tonight.
Community wikis add endless streaks as an income line, so if you run Endless, measure it separately — its random boards make per-run payouts less predictable than campaign clears.
The arithmetic is simple once you have a measured rate. If three evenings of dailies plus campaign clears earned you, say, 240 coins across the three sessions, that is 80 coins per session; a character priced at 400 coins by the game's own store screen then costs five sessions, and you can see the date instead of guessing it. The numbers in that example are illustration — the game shows your real balance and real prices in its own store screen, and those screen values always beat anything written here.
Because characters are cosmetic, the plan is reversible: nothing on any documented source says an unbought character ever changes payouts, so delaying an unlock never costs you progression — only the cosmetic you wanted today.
The documented facts point to a specific shape: income is routine-driven, spending is taste-driven, and solving skill is free.
Daily missions pay every day and stack with whatever campaign band you are clearing. A short daily session out-earns an occasional long one because the mission rewards refresh whether you grinded yesterday or not.
Wrong placements consume hearts, and recorded zero-heart runs show what running dry looks like. Careful scanning protects your earning rate better than any coin boost, because a wasted attempt earns nothing.
The community-listed passes (Heart + 1, 149 Robux; 2x Rewards, 249 Robux) change mistake tolerance and payout speed, not solvability. Every documented source agrees the grid itself never gets easier to solve.
No price has been published anywhere — not on the official listing and not on the community wikis as of the check. The honest plan is to measure your own next unlock: note your balance before and after buying, and you will have the only price that matters for your account.
The documented sources are Standard campaign clears, daily missions, and endless streaks, with coins named on the official listing's Standard row. Daily missions are the cheapest routine: they refresh every day and pay rewards on top of whatever campaign levels you were clearing anyway.
No. Both community wikis state characters are cosmetic and never change the grid — no rule, difficulty, or payout effect. Saving for a character is a collection decision, not a power decision.
chiidokugame.wiki lists Heart + 1 at 149 Robux and a 2x Rewards Pass at 249 Robux, and notes neither solves boards for you. They change comfort and payout speed, not your ability to solve — which is the skill Chiidoku actually grades.
Since characters are cosmetic, the decision is taste, not strategy: unlock a character you like now, or bank coins for a themed batch later. Nothing on any documented source says waiting earns a bonus.
