About One Hundred to One Slot

You can wager across desktop, mobile, and tablet devices from 10 cents to €50. You aim to land 5 of the same kind symbols on any of the 100 lucky lines. Five Free Spin symbols on a win line give you 1 bonus round. With it, you will receive multipliers starting from x1. If you re-trigger the feature you will increase the multiplier by x1 and this way it can reach x10.

The most lucrative result of bonus rounds is a total of 600 free spins with the last 100 – subject to an x10 multiplier. The most profuse payout on a spin, regardless if it’s normal or free, is 50 times your stake. This is a screen full of BAR symbols. Whenever you combine this with the biggest multiplier – x10, you can cash in up to 500 times the amount of your wager. For those playing with the largest allowed sum, this means €25 000.

The Design

The style of the game is traditional American. On the background of the reels on the left and right, you see the Great Seal of the United States. The eagle with the American flag on its back holding a banner with the Latin phrase: ‘out of many, one’. These are the same images you see on the one dollar bill. During some wins, you will see falling dollars.

It is very colourful in and around the grid. The dollar sign symbol is in red, the Free Spins is blue, and the BAR symbol is yellow. Around the grid, you see cells with the number of the free spins available. These are from 1 to 50 on the left and from 51 to 100 on the right each 2 with a different colour. The music you will hear while you play is electronic and reminds of the sounds of the old arcade games. The title’s variance is low to medium with an RTP of 95.36%.

One Hundred to One Gameplay

The slot resembles the land-based games and it is simplified as much as possible. There are only 3 symbols: the dollar sign, the BAR symbol, and the Free Spins. The most rewarding is the BAR. Five matching BAR symbols return the half of your stake. If you land 5 of the dollar signs on any of the 100 win lines, you’ll receive 0.3 times your bet.

You can wager from 10 cents to €50 on a spin. Given the fact that the pay-lines are a lot, you are likely to hit any of 100 regularly. To unlock the bonus round you have to arrange 5 Free Spin symbols on a win line. More about this feature read below.

Bonuses & Features

Once you hit 5 Free Spins symbols on a win line you will receive 1 bonus round and trigger the feature. It includes a multiplier starting from x1 on the initial spin. With every 5 symbols with Free Spins logos landed on a pay-line, you will increase the number of the bonus rounds. The multiplier increases as well with each new spin by x1. It starts from x1 and reaches to x10. For example, imagine you landed 5 Free Spins symbols on a lucky combination with a multiplier x2. Then, the next free round you just got will play with x3 multiplier and so on.

With each increase of the multiplier, you can get up to 100 bonus rounds. You can trigger 100 spins with x1 multiplier, then up to another 100 with x2 multiplier, and etc. Only the last 100 rounds’ wins you will multiply by x10. Thus, you have the opportunity to activate 100 bonus rounds at the start and these can get up to 600 in total. The wealthiest possible win is €25 000 – not bad for a low to medium volatile game!

The Bottom Line

What is unique in the game is the often triggering of the bonus feature and the plentiful pay-lines. It offers an attractive jackpot – €25 000 and frequent winnings in the main and bonus rounds. If you prefer better-paying video slots choose Novomatic’s Book of Ra Magic (with 5000 x bet) or Elemental Dragons (4000 x bet). Otherwise, load One Hundred to One using our free demo or the safe online casinos we trust. And get ready for a win!
