Plain’s own picture is one flight a day. The alternatives are separate sites.

Choose by the kind of guessing you enjoy: Estimania and Fermi ask for numbers; Size It Up asks for scale; Costcodle asks for a price. The remaining games use spatial judgement, riddles, timing, or crowd prediction. They share parts of Plain’s format without being the same game.

The table identifies the exact domain because more than one game uses names such as Size It Up and Rentguessr. Rentguessr here is the apartment game at rentguessr.fun listed by Alldle; rentguessr.com is a different domain and is not evidence for its modes. For a longer session, see unlimited alternatives. For the appeal of Plain itself, read the Plain review.

How I would pick

If you want another number, Estimania is the closest daily habit. If you want to practice ratio without a naming list, Size It Up’s unlimited mode is the one that stays open. If you want prices, Costcodle is a shop receipt, not a mountain. Centroid, Timingle, At What Point?, and Rentguessr are spatial, rhythmic, social, and housing games. Their descriptions help distinguish these different forms of guessing.

Questions

Which of these is closest to Plain?

Estimania: five numeric estimates a day. Size It Up trains the same ratio instinct with silhouettes instead of names.

Why only nine?

Nine entries cover different guessing styles, with the source strength visible in each row. The list is selective rather than exhaustive.

Is there a Plain versus page for each?

This comparison groups the games in one table. The official links lead to each game’s own rules and play page.
