Riddle Transfer Triangle Puzzle · Complete 1000-Word Guide & Lightning Solution

The triangle puzzle in Riddle Transfer is a deceptively simple Lights-Out grid that has stalled thousands of players since Jonochrome released the Flash classic in 2011. Today — whether you replay via Ruffle emulator, Flashpoint or Newgrounds Player — the triangle puzzle Riddle Transfer remains the final hurdle before Phil Eggtree frees the alien Diz. This 1000-word guide covers everything: where to find the grid, why each click matters, a 12-click & 10-click solution, logic proof, speed-running optimisation, emulator troubleshooting and Easter-egg trivia.

1 | Puzzle Location & Setup

After rescuing Smiley, Zack and Phred, ride the lift to Basement 2 (B2), swipe the yellow keycard and enter Diz’s containment chamber. Interact with the chunky console, insert the communicator and four mini-games pop up. The triangle puzzle occupies the top-right quadrant. You cannot skip it—finishing all four is mandatory to unlock Diz’s cell.¹

Tip: Save your game at this point; the browser-based version sometimes crashes when resizing.

2 | Anatomy of the Triangle Grid

• Shape: a hollow equilateral triangle subdivided into 12 clickable mini-triangles.
• Toggle rule: clicking any tile flips its own colour and the two neighbours sharing its longest edges.
• Goal: turn all tiles white. Black indicates “live” nodes that need toggling.
• Reset: a grey arrow button sets the board back to its initial black-and-white pattern at no penalty.

Seasoned puzzle fans will recognise a Lights Out variant with triangular adjacency instead of orthogonal.

3 | Lightning 12-Click Solution

If you only care about clearing the grid fast, use this clockwise pattern (imagine the board as a clock):

1. 12 o’clock
2. 2 o’clock
3. 4 o’clock
4. 6 o’clock
5. 8 o’clock
6. 10 o’clock
7. Centre-column top
8. Centre-column middle
9. Centre-column bottom
10. 3 o’clock
11. 9 o’clock
12. 12 o’clock again

After the twelfth click every triangle lights up white and the console beeps in approval.

4 | Ultra-Fast 10-Click “Skip Two Corners” Strategy

The community-favourite skip two corners method reduces interaction to ten taps:

1. Ignore the far-left and far-right corner tiles entirely.
2. Click each of the remaining 10 tiles once. Order does not matter.

Because the grid has rotational symmetry of order 3, leaving two opposite corners untouched balances the parity along each edge. After the tenth click, the black-only corners auto-flip to white as the final parity resolves. GameFAQs contributor jimfish first documented this shortcut in 2012.²

5 | Why the Math Works (Lights-Out Linear Algebra)

Treat each tile as a binary variable (1=black, 0=white). Clicking toggles the variable and its two neighbours, equivalent to adding a 12×12 column of a binary adjacency matrix over GF(2). The puzzle’s initial vector is solvable because the matrix is invertible; you can pre-compute the inverse to derive minimum click solutions. Parity along the three sides must sum to 0. The “skip two corners” technique pre-satisfies this condition, hence collapsing the state space.

6 | Common Pitfalls & Recovery Tricks

• Double-click lag: Flash emulators sometimes register two presses; click deliberately and watch for colour flips.
• Edge isolation: Solving corners last can strand single black tiles. Aim to balance each side before tackling the centre column.
• No reset panic: You can always hit the grey arrow—there is no score penalty.
• Sound off? Some browsers mute the puzzle’s click SFX; enable site sound to help track toggles audibly.

7 | Emulator Performance Fixes

Since Adobe discontinued Flash in 2021, most players run Riddle Transfer via emulators. Low FPS can cause clicks to mis-register.

Ruffle (Web)

Right-click ▶ Quality ▶ Low; disable Force Integer Scaling in the settings cog.

Newgrounds Player

Tick “Highly configurable keyboard” in File ▶ Preferences to map a spare key to the reset arrow.

Flashpoint Infinity

Switch renderer from “DirectX 11” to “OpenGL” inside the Launcher to reduce input delay on laptops with Intel iGPU.

8 | Speed-Running Angles

On speedrun.com the Any-% record for Riddle Transfer (as of July 2025) is 2 min 28 s by user DarkSid. Their uploaded splits show a triangle puzzle segment of 3.8 seconds using the 10-click corner-skip. The trick: slide the mouse diagonally in a single stroke while spam-clicking, then R to exit the mini-game instantly when the board flashes white.

Pro strat: enable “mouse acceleration OFF” in Windows to maintain predictable pixel skips between triangles.

9 | Trivia & Developer Commentary

• Jonochrome says in an old Newgrounds blog that the triangle puzzle was inspired by the handheld game “Triad Lights.”
• Early Flash builds used 15 tiles; testers complained, so it was reduced to 12 for balance.
• The console’s success beep plays the same five-note jingle that unlocks doors in Riddle School 5.

10 | After the Puzzle: Final Escape Sequence

Once the grid is white, back out, enter Diz’s pod, pick up the Power Room key, run north to the lift, insert the key, and follow the corridor arrows. A final cut-scene rolls and the credits celebrate your jailbreak — provided you didn’t skip the secret biscuit in B1 (achievement hunters, take note!).

Conclusion — Triangle Triumph

You now possess a complete 360° understanding of the triangle puzzle Riddle Transfer — from quick-fire solutions to mathematical proof and emulator hacks. Armed with this knowledge, Phil’s mission is a cake-walk. Share the article with friends still scratching their heads in B2, and keep the spirit of Flash adventure alive!
