Scope of this independent guide
dk7h.cc publishes editorial pages and its own Last Sign Switch 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. Ignore positions at zero. Compare each new nonzero position sign with the most recent nonzero sign. Raw score is the last row index from one through twelve where that sign changes, or zero when it never changes. 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
An all-right path and a right/left alternating path both score zero because no negative position is visited. The command sequence right,left,left,right,right,left,left,right,right,left,left,right changes nonzero sign at rows three,five,seven,nine and eleven; its raw score is eleven. A direction reversal while remaining on the same side is not a sign switch.
Exact expected gross return
Enumerate all 4096 equally likely outcomes 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. Ignore positions at zero. Compare each new nonzero position sign with the most recent nonzero sign. Raw score is the last row index from one through twelve where that sign changes, or zero when it never changes. One whole captured stake covers the path.
What is an example of the score?
An all-right path and a right/left alternating path both score zero because no negative position is visited. The command sequence right,left,left,right,right,left,left,right,right,left,left,right changes nonzero sign at rows three,five,seven,nine and eleven; its raw score is eleven. A direction reversal while remaining on the same side is not a sign switch.
What do the weighting modes change?
Low, Medium and High apply square-root, identity and square weights to a positive raw score. Zero stays zero, and each mode is separately normalised.
What does 96% describe?
Exact expected gross virtual return relative to captured stake under the stated probability condition. It is not a win probability or session guarantee.
