The "$20 Mode" has been absent since version 0.9.7 The accompanying readme advises "One game mode removed - it was only a matter of time as it contained copyrighted material", referring to the Brownz track that's used in that mode. The creepy sounds and page collector have been removed, there are static bars on the edges, and the ending is slightly different. There is also a "MH (Marble Hornets) Mode", viewing the gameplay as a ' Marble Hornets' entry. This is the only version in which the Player selects these modes in the "Options" portion of the menu screen, and this is also the only version in which two hidden modes can be played at the same time ("Daytime Mode" and "$20 Mode"). This is a reference to a fan-originated meme about Slender Man, stating that if a person gives Slender Man $20, he will leave the person alone. In this mode, gameplay is the same as "Normal Mode", except that if the player sees Slender Man a song called "20 Dollars" by American rap artist Ron Browz starts playing. After the credits roll, the player will have unlocked "$20 Mode". If the player beats "Daytime Mode" the ending will be the same as before, only the player wakes up at night.

"Daytime Mode" is simply during the day and without a flashlight.

After waking up, the player can walk around in the daytime for a few seconds before the credits roll. To unlock this mode, the player must beat the game on "Normal", in which the ending shows the player's character awaken in the daytime after collecting all eight pages and being caught by Slender Man. In Version 0.9.4 there is a "Daytime Mode" that can be unlocked. Once all 8 pages are collected, the sounds abruptly fade into silence. These sounds include a low droning sound (pages 3–4), a loud wind (pages 5–6), and then a mysterious and unnerving beeping sound (page 7). This sound is heard throughout the rest of the game, and gradually gets quicker as more pages are collected, as well as several other layering sounds. The end of this grace period is indicated by a repetitive stomping sound echoing in the background. However, the difficulty level increases the longer one goes without collecting any pages. There is also a grace period in the very beginning of the game, during which Slender Man remains inactive for only a few minutes, or until the player collects the first page. A few moments later the player awakens in the forest, now in the daytime, and can move around for a few seconds before the screen goes black and plays the end credits. However, instead of the normal death screen appearing, a slightly different version is played in which the static slowly fades out instead of abruptly stopping. Once all the pages are collected, one is allowed to walk around for a couple of seconds in total silence until Slender Man finally appears behind the player and ends the game. Įven if the player's character successfully collects all the eight pages, the Slender Man will continue to chase them. The game over screen shows Slender Man's face up close and blinking static pulses. A game over occurs when either the player has taken too long to find a note, the player stares at Slender Man for too long, or if Slender Man comes into contact with the player, which will turn them around and end the game. "Sprinting" allows the player to move faster than "jogging" does, but will also decrease the maximum stamina available for "jogging" and "sprinting". This then allows the ability to "sprint" to become available to the player. Slender Man will occasionally appear in the player's field of vision, accompanied with a loud piano slamming noise and/or static on the screen. The player's character has the ability to "jog", which will eventually tire out the player and make her wheeze if forced to go on for too long. The player is equipped with only a flashlight to see through the dark (its battery life is limited and will eventually shut down permanently if left on for an extended period of time). Slender Man moves by teleporting, creeping around the player, but only from a certain distance. As the player collects pages, the fog in the forest grows thicker, and Slender Man appears closer to the player's character, though the character's sprinting speed slowly increases as well. The player's objective is to collect all eight notes located in various areas of the forest while avoiding the Slender Man. Slender: The Eight Pages is set in the middle of a forest during the middle of the night, and is played from a first person perspective.
