Explore Microgaming gamesRock the Boat is a historical Microgaming classic slot with three reels and one centre payline. World Casino Directory lists it as Rock the Boat – Elvis; LCB preserves another screen of the same desktop edition. Both images show the musician portrait wild, lighthouse, guitar and bar symbols, and the same two-column coin paytable. These archive records do not establish current casino availability.
One centre line, two stake levels
The two paytable columns represent one or two coins on the single centre line. They do not activate a second payline. Multiply coins by the selected coin value to obtain the spin cost: the LCB screen shows two coins at value 5 for a 10.00 bet; the World Casino Directory screen shows two coins at value 1 for a 2.00 bet. No currency symbol establishes a universal dollar value.
Historical coin paytable
Only the highest winning combination on the centre line is paid, according to the instruction above the reels. Do not add the mixed-bar award to a higher matching-bar award on the same spin. The guitar rows refer to symbols on that line, not scatter prizes anywhere on the reels.
| Centre-line result | One-coin stake | Two-coin stake |
|---|---|---|
| Any one guitar | 2 | 4 |
| Three mixed bars | 3 | 6 |
| Any two guitars | 5 | 10 |
| Three single bars | 10 | 20 |
| Three guitars | 20 | 40 |
| Three double bars | 25 | 50 |
| Three triple bars | 50 | 100 |
| Three lighthouses | 100 | 200 |
| Three portrait wilds | 800 | 1,600 |
How the portrait wild changes an award
The portrait substitutes for all other symbols. The visible rule states that one wild pays 2× and two wilds pay 4× when substituting in a winning combination. These multipliers apply to the combination’s award, not to the player’s net profit. Three portraits use their own 800- or 1,600-coin row; do not apply an additional wild multiplier to that top row.
For example, at a two-coin stake, two lighthouses plus one wild pay 200 × 2 = 400 coins. At the pictured coin value of 5, that is 2,000 account units against a 10-unit stake, giving a net gain of 1,990 units if this is the highest payable combination. Two wilds with one lighthouse instead give 200 × 4 = 800 coins, or 4,000 units at that denomination. These are rule-based examples, not claims that either screenshot displays such a win.
Comparing the award with the full bet
At the World Casino Directory screen settings, a single guitar on the centre line pays four coins, or four units, against a two-unit stake. The net gain is two units. The four-coin number is therefore twice the full stake, not four times it.
The top two-coin award is 1,600 coins. At coin value 5, it converts to 8,000 account units against a 10-unit spin cost: 800 times the stake, with a 7,990-unit net gain. The second column doubles both the one-coin stake and the corresponding award; it does not improve this payout-to-stake ratio. The top prize is fixed in the displayed paytable rather than a progressive jackpot.
Features and edition limits
The documented classic edition has no separate free-spin or bonus round. Its principal feature is the multiplying substitution wild. The screenshots show two denomination settings but not the complete available range. This review therefore does not assert universal current stake limits, a verified RTP or present-day availability. Check the exact edition’s own rules where it is offered.
Rock the Boat questions
Does the second coin enable a second line?
No. Both stake levels use the single centre payline.
What does one portrait wild multiply?
It doubles the qualifying combination’s coin award. Two substituting wilds multiply that award by four.
Do three wilds receive an extra multiplier?
The paytable gives them a separate top award of 800 or 1,600 coins. Do not multiply that row again.
Can a single guitar pay?
Yes. On the centre line, one guitar pays two coins at a one-coin stake or four at a two-coin stake, subject to the highest-win rule.
Is 1,600 coins the same as 1,600 times the bet?
No. That award uses a two-coin stake, so it equals 800 times the total bet.
Are the archived cash values current casino limits?
No. The screens demonstrate particular historical coin values, not a universal current currency, stake range or availability.
