Shared controls
Every game offers Easy, Medium and Hard, New Puzzle, Hint and Reset Puzzle. Most games use Solution for full practice; games with a more interactive teaching flow may label that control Guide. Regular Play creates fresh boards. Daily Challenge uses the same board for everyone for that UTC date and difficulty.
| Control | What it does | Ranking effect |
|---|---|---|
| Hint | Shows a limited next action or short forecast. | Still ranked, with a points penalty. |
| Solution / Guide | Shows a full practice aid on the board. | Current attempt becomes practice-only. |
| Reset Puzzle | Returns the current board to its starting state. | The same assisted board remains practice-only. |
| New Puzzle | Starts a fresh board. | Returns to ranked eligibility when a verified attempt is available. |
Echo Step
Move purple YOU while cyan Echo repeats each accepted move after a delay. Medium and Hard add crooked timing routes, false shortcuts and delayed traps before YOU and Echo can finish together.
- Move purple YOU toward P. Echo repeats each accepted move after the displayed delay.
- Purple striped cells block YOU only. Cyan striped cells block Echo only. Dark striped cells block both.
- Reach YOU → P and Echo → E on the same turn. Reaching one goal alone does not finish the puzzle. Medium and Hard may require leaving P and returning at the right moment.
- If Echo repeats into a blocked cell, leaves the board, or hits YOU, use Retry. Hint shows the next three moves; Guide teaches the puzzle step by step.

Maze
Navigate a fresh maze with real decision pressure, deep false branches, deceptive dead ends and increasingly demanding routes.
- Move from the purple start marker to the green finish.
- Hold and drag through open corridors, swipe on touch, click an adjacent cell, or use Arrow/WASD keys.
- Hard boards increase decision density, deep false branches and late-route traps — not only board size.
- Hint draws a short next-route guide. Solution draws the full route and makes that attempt practice-only.

Number Path
Build one continuous path through an irregular board while landing on numbered checkpoints at the exact path step.
- Start at 1 and move to orthogonally adjacent open cells.
- A numbered checkpoint is the exact step number where your path must land on that cell.
- If a branch is wrong, tap or drag back onto any earlier path cell to trim the route to that point, then continue in a different direction.
- Hint reveals a real next action. Solution shows one full numbered route for practice.

Color Connect
Link matching endpoints across solver-verified boards where tempting short routes, shared space and route dependencies force real backtracking instead of obvious lane-by-lane play.
- Drag from one colored endpoint to its matching endpoint.
- Paths remain after release and may not overlap, cross blocked cells, or pass through another color endpoint. Every open cell must be covered to finish.
- Medium and Hard are accepted only after a solver tests alternate routes, dead ends and greedy shortcuts; Hard uses 11 color pairs and deeper route dependencies.
- Hint guides a short section of one route. Solution shows all ghost routes at once for practice; colors may be traced in any order.

Lights Out
Press a light to toggle it and its neighbors. Difficulty is calibrated by the true minimum number of presses.
- Tap a light to toggle it plus its up, down, left and right neighbors.
- Your goal is to switch every light off.
- Difficulty reflects the board’s minimum solution length, not only board size.
- Solution highlights one shortest set of presses. The highlighted cells may be pressed in any order and the guide recalculates after every move.

Loop Puzzle
Build one closed loop from strategically selected clues. V4 shapes avoid easy perimeter routes while Hard boards favor meaningful 2/3 anchors, sparse isolated 0s and deeper deductions.
- Tap grid edges to draw one continuous closed loop.
- A number is the exact count of that cell’s four sides used by the loop. Blank cells have no clue, so any number of their sides may be used.
- Any single loop satisfying every visible clue is accepted; edge order never matters. Hard boards use more turns, shorter straight runs and strategic clue placement instead of simply hiding more clues.
- Hint marks one exact edge to add or remove. Solution shows ghost edges for one valid loop and makes the attempt practice-only.

Bridges
Connect numbered islands with one or two horizontal or vertical bridges. Match every island number, never cross another bridge, and finish with one connected network.
- Tap one island, then a highlighted island to add one bridge. Repeat the same pair to make a double bridge. Tap an existing bridge to remove one.
- The number on an island is the exact total of bridges touching it. Two islands may share at most two bridges, and bridges can never cross or pass through an island.
- A puzzle is solved only when every number is exact and all islands belong to one connected network. Matching numbers in disconnected groups is not enough.
- Hint shows one specific add/remove action, highlights the connection and explains the logic before you choose Apply Hint. Solution shows missing bridges in cyan and wrong bridges in red for practice.
