Reaching a Final Score of 3.1e151 in RACCOIN, a Coin Pusher with Roguelite Elements

Early on, the game plays like an ordinary coin pusher. You start with 20 regular coins to drop in, and you drop them a little at a time by clicking left and right. Each coin that falls off earns points, and once you reach a set amount, you can move on to the next round.

Dropping coins also earns a currency called "tickets." After each round there's a shopping phase, where you use tickets to buy items and special coins. How you strengthen the board through these purchases is the heart of the roguelite side of the game.

On the first shopping trip, the streamer bought the "Bunny Coin," which multiplies when coins of the same kind touch each other, and the "Rain Pillow" (an umbrella), which rains down whichever coin has been purchased most often. That used up all their tickets.

In round 2, they dropped in the purchased coin at a time of their choosing and then used the umbrella. Bunny coins poured down all at once, bunnies that touched each other bred, and the newborn bunnies bred in turn. Once the multiplication settled down, they dropped in regular coins and cleared the round. Judging the umbrella to be powerful, the streamer kept buying umbrellas in later shopping phases.

From round 3, the elements on the left side of the screen also start working, and continuing to drop coins triggers a lottery. This time they won a "Coin Tower," and a tower of 48 coins was built in the center. They pushed it over and cleared round 3 as well.

As the bunnies' effect began to wane, the streamer next bought the "Work Coin." Tickets can be exchanged for regular coins, but while Work Coins are on the board, each exchange earns 5 extra tickets per Work Coin. This time they managed to get 16 Work Coins onto the board, so a single exchange yielded 80 tickets. Since you can exchange up to 7 times per round, they earned 560 tickets in that round alone. They also met the quota by dropping in the coins obtained from the exchanges.

However, Work Coins reportedly break down if they work for too long, inflicting debuffs on the board. The streamer "used them up and tossed them" before that could happen and switched to the next coin.

The newly chosen coin was the "Whirlwind Coin," which creates a tornado that sucks up coins. When dropped in during round 5, it produced a much bigger tornado than the streamer expected, lifting up nearly every coin on the board. The tornado moves a little toward the exit each time a coin is dropped in manually, but to make use of it for as long as possible, the streamer stopped dropping coins at this point.

Meanwhile, the tornado blew away a "Bad Coin," which appears periodically, earning one upgrade as a reward. The streamer chose a bag that expands item slots, allowing them to use the umbrella three times at once.

In the following shop, they bought umbrellas in bulk while looking for a coin to pair with the Whirlwind Coin. What they found was the "Multicoin," which triples the score of anything it touches. Dropping it in to aim for synergy with the tornado produced a mass of coins making a deafening racket. The streamer remarks that they had thought it would be a relaxing game to watch at a leisurely pace, but it was actually as noisy as an arcade, and a game where you catch your breath at each shop.

At this point, the quota for the next round was 4,500 points. The streamer judged that clearing it would be easy just by raining down Multicoins with the umbrella and rubbing them together inside the tornado. In fact, single coins came to be worth billions of points.

With three rounds left, the streamer turned to the "Saw Coin" to push their score even higher. It cuts anything it touches into four pieces, and the idea was to use it to multiply Multicoins. Once it was dropped in, the game started to become unstable.

Here the streamer exploited the umbrella's mechanics. The umbrella rains down the most-purchased coin, and in the event of a tie, the most recently bought one takes priority. Since they had only bought each coin once up to that point, the umbrella's target had switched to the Saw Coin when they bought it. So they bought the Multicoin a second time, returning the umbrella's target to the Multicoin.

Adding even more Multicoins to the already lagging game created a situation where a single coin falling looked likely to be worth around 100 million points. However, the board became so stable that coins hardly fell, and only after waiting a while did one finally drop, meeting the quota.

There were no coins they wanted in the last shopping phase, so they bought as many umbrellas as they could and headed into the final round. In the final round, sound effects played nonstop, and with the scoreboard hidden from view, the displayed coin values kept on rising.

The streamer could have waited for the board to settle, but decided to end it. As explained earlier, dropping in coins moves the tornado forward, so they used that to clear out the tornadoes. The score at this point was 1.2e112. Since it seemed some high-value coins were still left, they waited until all the tornadoes had passed, and the score finally reached 3.1e151.

The game ended with this round. The streamer reflects that they'd been playing a lot of brain-intensive games lately, so it was a relief to get to melt their brain for a change. They also note that, as of the video, the game is in playtesting.
