Ice Fishing strategies, made readable

Historical replay, step by step

First choose what you want the test to explain

A bankroll chart is easier to understand when it answers one question: how would a fixed set of rules have changed a starting balance over these recorded rounds? You choose the target, base unit, starting bankroll and progression. The test applies those rules in chronological order.

Keep the selected history constant while comparing systems. If you change both the strategy and the sample, you no longer know which change produced the different result. Write down your assumptions before looking at the winning sequence.

Flat stake

The reference case

1 → 1 → 1 → 1

Choose one target and use the same unit every recorded round. Keep the unit unchanged after wins and losses. Stop when the chosen sample ends or the model cannot fund the next stake.

This makes total intended exposure easiest to inspect. Over 100 rounds with a 10-unit stake, the planned sum of stakes is 1,000 units; the final balance still depends on the outcomes and payout assumption.

Martingale

Double after a loss

1 → 2 → 4 → 8 → 16

Begin with one unit. After a losing round, double the next stake. After a target hit, reset to the base unit. Set a maximum permitted stake before any practical use; the basic replay also stops when the remaining bankroll cannot cover the planned stake.

Five consecutive losses consume 31 units and require 32 for the next step. Ten consume 1,023 and require 1,024 next. An overdue fish does not increase its next-spin chance, and variable payouts do not give the classic even-money recovery identity.

Paroli

Raise after a win

1 → 2 → 4 → reset

Begin with the base unit. After a hit, double. Reset after a loss or after three consecutive hits in this implementation. Keep the sequence cap fixed rather than extending it when the chart looks favourable.

This moves larger stakes after wins instead of losses. It changes exposure timing, not the chance of another hit. A historical cluster is not evidence that the next fish will continue it.

D’Alembert

One unit up or down

1 → 2 → 3 → 4 after losses

Start at one unit. Add one unit after a loss. Subtract one after a hit, with the base as the minimum. Keep the selected target consistent while evaluating the sequence.

The growth is slower than doubling but is still growth. A long run can raise both the next stake and total losses. A target hit is not necessarily enough to recover all earlier losses.

Fibonacci

Follow a growing sequence

1 → 1 → 2 → 3 → 5 → 8

Start at the first position. Advance one position after a loss and step back two after a hit, without moving before the beginning. The next stake equals the current sequence value multiplied by the base unit.

The progression can become unaffordable despite its slow opening. Do not silently cap the sequence and call it the same system; any stake cap is an extra rule that should be reported.

Labouchere

A money-unit cancellation list

1, 2, 3, 4 → stake 5

For a paper example, write a fixed unit list. Stake the first plus last entry, or the sole entry if only one remains. After a modeled win remove those entries; after a loss append the stake to the list.

A missing fish is not a monetary debt. Variable game payouts also mean the usual cancellation story cannot simply be pasted onto every bonus result. This system is explained here but is not one of the five interactive replay options.

Oscar’s Grind

A small session target

Keep the stake after a loss

Set a one-unit profit target for a paper series. Start at the base stake, keep it after a loss and, in the common version, increase after a win only while the series remains below the target. Stop at the predetermined target or separate limit.

A target is an intended stopping point, not a guarantee. Reaching a bonus and recovering the complete series loss are different events. This system is descriptive here rather than implemented in the interactive replay.

Read the bankroll line in four checks

When two strategies stop at different spins, compare that difference as well as their final balances. A stopped progression has not survived the same number of bets as one that completed the sample. A low final loss after an early stop is not automatically superior performance.

Sample return is modeled gross returns divided by modeled stakes. It is sensitive to the target, stake sequence, records and payout assumption. Calling it the casino’s “live RTP” would imply more than the available data establish.

Use a heatmap to describe, not to trigger a bigger stake

Each heatmap row groups a block of recorded spins, and each cell counts a multiplier range. It makes changes in the recorded distribution easy to see. It does not validate a rule such as “red has been missing, so double now”.

A better research exercise is to define a rule before testing it, keep a flat-stake baseline and reserve a later sample for a separate check. Report the failed sequences as well as the successful ones. Even a promising historical result does not turn independent outcomes into a forecast.

If the only goal is to understand the history, you can do all of this without wagering. See the budget guide for a simple exposure calculator and stopping considerations.
