Cash Stamp Overview

Cash Stamp is an online release from Konami Gaming, with a permanent jackpot panel to the left of the reels. The panel lists GRAND JACKPOT at the top and MEGA, MAJOR, MINOR and MINI beneath it, and it is visible from the first spin.

Pokie Theme & Visuals

The shark is the Wild, the pearl in a shell is the Scatter and the gold vault is the Bonus symbol. The treasure chest is the top regular symbol, followed by the porcupine fish, clownfish, jellyfish, turtle and the A, K, Q and J royals. The reel frame carries the label 50 LINES.

During the Bonus Game the screen switches to a 5x5 board of 24 reel positions with the Vault in the centre. The Line Hit Meter sits in the top left corner.

RTP & Volatility

The Cash Stamp casino runs at 96% RTP in its online version. Konami sets the cabinet and the online build separately, and 96% is the online figure. Volatility is high: the top line pay is 300 credits for 5 Wilds at the 75-credit stake. Most of the return sits in the Bonus Game and the Grand Jackpot, up to the 10,000x max win.

With stakes from AU$0.75 to AU$8, a session budget sized to wait for six gold vaults fits the pace. MEGA, MAJOR, MINOR and MINI prizes scale with the bet level as well.

Bonus Game Board

Six gold vaults open the board. The trigger is 6 or more Bonus symbols on screen after the reels stop, including after a nudge. Each vault then turns into a Gold Coin worth 20, 50, 70, 100, 120, 150, 250 or 450 credits multiplied by the bet level. The coin total is written onto a Vault symbol at the top of the screen. The Vault moves to the centre, and a board of 25 positions opens: 24 reel positions around one held Vault.

The board has 12 lines: 4 horizontal, 4 vertical, 2 diagonal, plus the centre row and centre column as lines 11 and 12. Lines are evaluated in strict order from 1 to 12. The Vault stays in the centre for the whole feature and shows the running credit prize.

3 games are awarded at the start. If at least one prize or multiplier symbol lands, it is held and the remaining games reset to 3. Board reels show Gold Coins and blank positions.

When all 5 positions on a line hold prize symbols, their values are added and collected on the centre position of that line. That centre position is then held, and the other 4 positions on the line spin again in later respins. The same line can therefore close more than once. A prize symbol on the intersection of two closed lines is counted in each of them. Every closed line adds one hit to the Line Hit Meter.

The Bonus Game ends when games remaining reach 0 or when the Grand Jackpot is awarded. All credits on Gold Coins and on the Vault are paid at the end. The board uses its own reel sets, and the feature can also start inside the Free Game Feature.

Locked Coins & Line Multipliers

Locked MEGA, Locked MAJOR, Locked MINOR and Locked MINI coins can land on every board reel except those on lines 11 and 12. The same limit applies to the Locked 3x and Locked 2x multipliers. While a coin is locked its prize is unpaid. If all 5 positions on a horizontal, vertical or diagonal line fill with symbols and one of them is a Locked Coin, that coin unlocks.

If a line fills with prizes and carries at least one multiplier symbol, each prize on that line is multiplied by the multiplier(s). The sum is then collected on the line centre. A multiplier on the intersection of two closed lines multiplies the prizes on both. Multiplier symbols stop appearing on the board reels once the total bonus value exceeds 1,000,000 credits multiplied by the bet per line. That total includes prizes on visible Locked Coins.

Nudge Feature

In the base game a reel can shift one position up or down after it stops. If the shift brings 6 or more gold vaults onto the screen, the Bonus Game starts from that spin.

A nudge never reduces the total screen win: it adds to it or leaves it unchanged. Manual reel stops do not change the result.

Bonus Rounds

The pearl Scatter starts the Free Game Feature, and the gold vault starts the Bonus Game. The Bonus Game can begin during free games. Scatter does not appear on the board reels, and free games cannot start while the board is running.

Free Game Feature

3 Scatter symbols award 6 Free Games. Scatter lands on reels 2, 3 and 4 only and pays in any position. 3 Scatter return 100 credits at the 75-credit stake on top of the trigger. Inside the feature, 2 Scatter add +2 games and 3 Scatter add +6.

Cash Stamp free games with royals removed from the reels and the remaining free games counter

The A, K, Q and J royals are removed from the free game reels. Only the shark Wild, Scatter, treasure chest, porcupine fish, clownfish, jellyfish, turtle and gold vault remain. Lines therefore close with symbols from the upper half of the paytable. The feature runs on its own reel sets at the same total bet as the triggering spin.

Bonus Game Inside Free Games

If 6 or more gold vaults land during the Free Game Feature, the same 25-position board opens under the Bonus Game Board rules. When the board closes, the remaining free games continue.

Grand Jackpot & 15 Lines Award

GRAND JACKPOT is the progressive at the top of the panel. It can be awarded at random at the end of any base game spin, and the chance changes with the bet level. Inside the Bonus Game, the 15 LINES AWARD fires when the Line Hit Meter reaches 15 or more closed lines. The board then ends at once with the Grand Jackpot.

The board holds only 12 lines, so 15 hits require some lines to close again after their centre is held and the other positions respin. The jackpot value and its reset amount scale with the denomination; at the time the demo was recorded the panel showed AU$11,261.55.

Similar Slots by Konami

Bull Rush is the closest relative: a 5x3 Konami game with 50 fixed lines and a Bull Blitz hold-and-spin that fills up to 15 positions. The Cash Stamp slot uses a 25-position board with 12 lines and a Line Hit Meter instead. A held coin can count toward more than one line, and the meter itself can award the Grand. The RTP on each card below is the online figure, since Konami tunes its cabinets separately.

FAQ

Land 6 or more gold vaults on screen after the reels stop, including a vault brought in by a nudge. Each vault becomes a Gold Coin worth 20 to 450 credits multiplied by the bet level, and the 25-position board opens with 3 games.

It counts every line that fills with prize symbols and collects to its centre. When the count reaches 15, the 15 LINES AWARD ends the board and pays the Grand Jackpot. Since the board has 12 lines, reaching 15 needs repeat closures of lines whose centre is already held.

A Locked Coin opens when all 5 positions of the horizontal, vertical or diagonal line it sits on are filled with symbols. Locked Coins never land on lines 11 and 12, the centre row and centre column. Until unlocked, the MEGA, MAJOR, MINOR or MINI prize is unpaid.

A multiplier applies only to prizes on a closed line that contains it. If the 2x or 3x coin sits where two closed lines cross, the prizes on both lines are multiplied. Multiplier symbols stop landing once the bonus total passes 1,000,000 credits multiplied by the bet per line.

3 Scatter pearls on reels 2, 3 and 4 award 6 free games. During the feature, 2 Scatter add 2 games and 3 Scatter add 6. The A, K, Q and J royals are removed from the free game reels.

Yes. The rules allow the Grand Jackpot to be awarded at random at the end of any base game spin, with no board or feature required. The chance of that award changes with the bet level, and the jackpot value scales with the denomination.

The minimum stake is 75 credits, which equals AU$0.75 at the AU$0.01 denomination. Bet Per Line levels run up to AU$8 per spin, and every paytable figure is quoted from the 75-credit stake.
