How to Play pokie

The pokie has a small 5x3 field on which 9 simple symbols and 5 kinds of special symbols can appear. There are 3 types of spins: simple, free spins and respin round. In the simple game, payouts are formed on 30 lines, which pay according to the classic principle - only from left to right from the first reel, and for 3+ symbols in a line. In the free spins, the pokie pays without lines, for 3+ symbols in a row on 3+ reels, starting from the first left. Only Prize and Super Prize symbols participate in the respin round.

You can choose a bet from 0.20 to 50.00. The step between bets is very large. You can win a maximum of x3910 per respin round or freespins.

Symbols, Wild, Scatter

Here are the purpose and rules for all the wildcards:

  • Prize. Blue coin with a random multiplier ranging from x1 to x100, or 3 jackpots (except Grand). Does not participate in free spins. In simple spins, 6+ such icons trigger the J Mania round.

  • Super Prize. In simple spins, only 5 will appear on reel 5. If 5+ Prize + 1 Super Prize appear on the field, the Super J Mania enhanced respin round will be triggered. In the Super J Mania round, the Super Prize can have a multiplier from x5 to x100, or any of the jackpots including the Grand.

  • Scatter. A sparkling blue stone. Can only appear on reels 1, 3 and 5. If 3 Scatter falls on the field - the gambler receives a payout x1 of the bet + 10 free spins.

  • Super Scatter. A sparkling red gem. Can only appear on reel 5. If 2 simple Scatters and 1 Super Scatter appear on the field - the gambler receives a payout of x1 + 10 enhanced free spins (Super Free Games).

  • Wild. Pays in the combination of any simple symbols, if it appears in its composition. In enhanced free spins it increases to the full height of the reel (Expanded Wild feature).

Bonus games

Here are the rules for all the bonus features in J Mania Diamonds:

  • Buy Feature. For x200 of the bet from here you can trigger a free spins package.

  • J Mania. The Respin Round is triggered when 6+ Prizes appear on any cells in the simple game. These 6+ Prizes are transferred to the Respin Round on their cells. The remaining cells are empty. The gambler has 3 respins to play. There is a chance that new Prize symbols will appear on the empty cells per spin. If at least 1 Prize appears - the gambler gets 3 more respins. If for 3 spins no 1 new Prize will not fall out, the round ends. The amount of multipliers on the field is paid to the gambler. If all cells are filled with Prize symbols - the round ends, the gambler receives the amount of multipliers + Grand Jackpot.

  • Super J Mania. Improved Respin Round. Works by the same rules as the simple J Mania, only you need to catch 5+ Prize + 1 Super Prize to trigger it. Differences of the improved respins: only Super Prize symbols fall on the field (and they have higher multipliers, and there is a chance that the biggest jackpot will appear).

  • Expanded Wild. In the Super Free Games round, all Wilds are stretched to the full height of the reel.

Free spins

The pokie has 2 kinds of free spins: simple and Super. The difference between them is that in the Super package, all Wild signs are stretched to the height of the entire reel. In both types of free spins, payouts are formed not by lines, but for the appearance of identical signs on 3+ reels in a row from left to right (that is, signs can appear at any height). The FS can be triggered via the Buy Feature for x200 of the bet, or won for the appearance of 3 Scatters on the field. The Super pack is triggered if 2 simple Scatters and 1 Super Scatter appear on the field.

If 3 Scatters appear during the free spins, the gambler will get +10 spins.

Jackpots

J Mania series pokies play 4 non-progressive jackpots: x10, x50, x250, x1000. Any of them can only be won in the J Mania or Super J Mania rounds. In the simple round, the first 3 jackpots can fall on Prize symbols, and the biggest jackpot can be given if all 15 cells are filled.

In the advanced round, all 4 jackpots can fall on Super Prize symbols, and the biggest prize is given if all 15 cells are filled.

RTP, Volatility & Hit Frequency

If you want to understand how good the return on bets is, here are the characteristics that affect it:

  • RTP is above average at 96.31%.

  • Average volatility (the size and frequency of payouts are balanced - large wins, several times the bet, are not uncommon).

  • Payout frequency - up to 20 times for every 100 spins.

Strategy: How to Win at pokie

To come up with and use a strategy, you need 2 things: for the game to work according to natural rules, and to be able to influence the gameplay. Pokies have neither of these. The principle of their work is based on the random selection of combinations from tens of thousands of possible (they are already collected and added to the database, from which are simply selected when you click on Spin). Nothing depends on the gambler: he can only choose the bet and start the reels. Therefore, strategies in pokies do not work.

Interface

The pokie has a very simple design with a constantly moving background. The field and symbols are large. Above the field, jackpot sizes are displayed, which change as you increase or decrease your bet. To the left of the field is the Buy Feature button. The current launch price is written on it. The balance is shown on the bottom border of the screen, on a black background. To the left of the balance are buttons to adjust the sound and to go to the rules page (?). The rest of the interface elements are gathered in a horizontal block below the field. It is divided into 3 parts. In the center is the Win-window - when a winning combination falls on the field, this block shows the size of the payout. On the left there are 3 buttons - a link to the payout table (i) and buttons - and + to change the bet. On the right there are 3 more buttons to control the game - start manually, start auto spins and Turbo to speed up/slow down the reels. If you are interested in the slot - before you start playing for money I recommend:

  1. Go to the paytable and familiarize yourself with how much each of the symbols pays.

  2. Play before the J Mania round starts to see how it works.

  3. Set up autospins so you don't have to hit the start button manually. For autospins, you can enable stopping by the number of spins (10-100), by the size of 1 win, the amount of wins or the amount of losses.

Mobile Compatibility

For phone or tablet (Android and iOS), the developers have added a mobile version. It does not need to be enabled: it will load automatically when the gambler opens the pokie from a suitable device. The interface has been enlarged to fit the orientation and aspect ratio of the screen, so you can play on both small phones and large tablets.

Editor's opinion: the pokie is not bad, but it has nothing unique or very interesting. The small field and not very frequent payouts will not appeal to players who like variety while playing.
