Scope of this independent guide
688pg.cc publishes editorial pages and its own Path Checksum Plinko browser simulator. A matching name or search query establishes no outside operator, official domain, licence, app, commercial catalogue, support contact or regional availability.
The simulator uses free virtual coins with no cash value. There are no deposits, withdrawals, commercial accounts or prizes here. Its results establish no external game mathematics, financial safety or commercial affiliation.
The actual simulator rules
A ball starts at signed position zero and takes twelve independent fair left/right steps. Encode right as one and left as zero. Start checksum h at zero; after each step update h=(2h+bit) modulo five. Raw score is final signed position squared only when the final checksum is two; otherwise raw score is zero. A qualifying checksum with final position zero still gives zero. One whole captured stake covers the path.
These are this guide's original rules. Visual resemblance, game-category names and search snippets provide no evidence about an external commercial game.
Worked scoring examples
All-left commands leave checksum zero and score zero. All-right commands encode 4095, which is zero modulo five, and also score zero despite endpoint twelve. Eleven left commands followed by one right give checksum one and score zero. Ten left commands followed by right then left encode two, finish at minus ten and score 100. A final qualifying checksum is essential; intermediate checksum two creates no credit.
Exact expected gross return
Enumerate all 4096 equally likely twelve-choice patterns and calculate a separate exact mean for each weighting mode. Choose Low, Medium or High before a round. Positive raw scores receive square-root, identity or square weighting respectively; zero remains zero.
Gross virtual credit equals the whole captured stake times 0.96 times observed weight divided by the corresponding exact mean. Every mode has 96% exact expected gross return. There are no separately paid row shares. The stake was deducted at launch, so gross credit includes the stake component and is not net profit.
Modes preserve positive-score frequency while changing positive credits after normalisation. The expectation is neither a 96% chance of winning nor a session-balance guarantee. Past results do not make a favourable next outcome due.
Captured settings and the persisted wallet
A new browser wallet starts with 1,000 free virtual coins. Settled balance and fractional-credit carry persist in localStorage. Reload does not replenish settled funds; clearing cache may leave localStorage intact. Fractions accumulate before whole coins are credited.
Up to six separately priced drops may be in progress. A drop retains its captured settings; changing controls affects future launches only. Auto launches at most ten rounds; Stop cancels future launches while active results settle. Refill remains locked until all active results and queued launches finish. Optional manual refill is available while idle with balance below ten; it sets balance to 1,000 and preserves carry. It is not automatic and does not add 1,000.
Frequently asked questions
Is this an authenticated operator website?
No. This guide provides its own simulator and authenticates no outside commercial affiliation.
How is raw score defined?
A ball starts at signed position zero and takes twelve independent fair left/right steps. Encode right as one and left as zero. Start checksum h at zero; after each step update h=(2h+bit) modulo five. Raw score is final signed position squared only when the final checksum is two; otherwise raw score is zero. A qualifying checksum with final position zero still gives zero. One whole captured stake covers the path.
What is an example of the score?
All-left commands leave checksum zero and score zero. All-right commands encode 4095, which is zero modulo five, and also score zero despite endpoint twelve. Eleven left commands followed by one right give checksum one and score zero. Ten left commands followed by right then left encode two, finish at minus ten and score 100. A final qualifying checksum is essential; intermediate checksum two creates no credit.
