How access works

The waitlist stays open through November 30. On December 1, 200 people are selected. The product launches for them on December 12. Everyone else stays on the list until January 1, when each person can send one invite. One invite per person.

1. October 29–November 30, 2026

   OPEN

   Waitlist opens

   The waitlist stays open through November 30. Registering records your interest. It is not access to the game.

   What to expect. You can register your interest, read how Two5 is being built, and follow launch announcements. Joining does not reserve a place. The list closes for this draw on November 30.

2. December 1, 2026

   UPCOMING

   200 selected

   Two hundred people are selected from the waitlist, and a WhatsApp invite is sent to them. The product is not live yet. Selection is a random draw, not a test of skill.

   What to expect. Selected people get the WhatsApp invite on December 1. Everyone else stays on the waitlist. Selection does not open the product that day.

3. December 12, 2026

   UPCOMING

   Product launch for the 200

   The product launches only for these 200. Nobody else can play that day.

   What to expect. The selected players can use the live product. Other people stay on the waitlist until January 1, when each person can send one invite.

4. January 1, 2027

   UPCOMING

   One invite per person

   From January 1, each of the 200 can invite one person to play. One invite per person.

   What to expect. That invite is for one new player. One person cannot send more than one. This is the first time someone outside the 200 can be invited in. An invite can fail if it expires, is withdrawn, or breaks the published rules.

5. After January 1 — date to be announced

   PLANNED

   Progressive access waves

   Later waves depend on reliability, player feedback, product readiness, whether rounds are worth replaying, and whether the team can support more players.

   What to expect. There is no date for open registration. The waitlist remains the way to be considered for a later wave.

6. Future development

   PLANNED

   Training and competition evolution

   These are directions under consideration. They are not delivery commitments, and they are not features you can use today.

   What to expect. Possible later work includes more training arenas, more challenge types, a clearer performance history, adaptive difficulty where it helps, daily challenges, friend challenges, and fuller progress summaries.

What happens after you join?

1. 1

   Register

   Submit your email through the waitlist form. The current form also asks for your name and age so the account can be created.

2. 2

   Wait for selection

   The waitlist stays open through November 30. On December 1, 200 people are selected and sent a WhatsApp invite. Most people on the list will not be selected.

3. 3

   Play, then invite

   If you are selected, the product launches for you on December 12. From January 1, you can invite one person to play. One invite per person.

If you are not selected, you can remain on the waitlist for future access waves. Joining does not guarantee a particular selection date.

Help shape the first version.

Founding players may report bugs, share usability notes, answer short product surveys, compare the live flow with what they expected, and suggest improvements. A suggestion is not a commitment to build it.

• Selected on December 1, with a WhatsApp invite sent that day.
• Product launch on December 12, only for these 200.
• From January 1, one invite per person.
• Early access to future features when they are offered.
• A chance to help improve the experience before more people get in.

Training should have a purpose.

Two5 intends to build challenges around defined cognitive task demands, rather than labelling arbitrary games as brain training. The principles below are a design standard. They are not a clinical claim.

1. 01

   Specific task demands

   Identify what a challenge actually asks the player to do, instead of labelling any short game as brain training.

2. 02

   Useful feedback

   Show the result, and make the relevant miss or the shape of the performance readable.

3. 03

   Progressive challenge

   Where it fits the task, difficulty can rise as performance improves. That is a design aim, not a claim that every launch game already adapts.

4. 04

   Variety

   Use different challenge structures so one narrow skill is not treated as the whole of cognitive ability.

5. 05

   Honest measurement

   A better score on a game is a better score on that game. It is not, by itself, a measure of general intelligence or real-world ability.

Research on cognitive training reports benefits for some trained or related cognitive outcomes, but results vary. Improvements on a particular game do not automatically demonstrate broad real-world transfer. Two5's own effectiveness has not been clinically established.

• Zhu et al. (2025). Cognitive training during midlife: a systematic review and meta-analysis. Neuropsychology Review. The review looked at cognitive training in healthy middle-aged adults, including game-based training, and reported gains on some measured domains in that group. Near-transfer and far-transfer were treated separately. It is not a study of Two5.
• Systematic review of serious games for training attention and executive functions. Cited as background on that research area. It does not evaluate Two5, and its findings should not be read as proof that this product works.
• Google Search Central. SEO Starter Guide. A reference for keeping these pages crawlable. It is not evidence about mental training.
