2048 STRATEGY LAB
Which 2048 strategy works better?
Instead of repeating “keep the biggest tile in a corner,” this page tests the idea. Four automated policies played 500 games each on a standard 4×4 board using the usual 2/4 spawn probabilities.
In this benchmark, a corner-chain policy with one-step lookahead averaged 9,474 points — about 8.65× the random policy — and reached the 2048 tile in 8% of games.

Benchmark results
Each row contains 500 independent games. P90 is the score exceeded by the best 10% of runs.
| Strategy | Avg score | Median | P90 | Best | Avg moves | Reach 512 | Reach 1024 | Reach 2048 |
|---|---|---|---|---|---|---|---|---|
| Random valid move | 1,095 | 1,036 | 1,688 | 2,932 | 119 | 0.0% | 0.0% | 0.0% |
| Merge-first | 1,973 | 1,756 | 3,072 | 5,512 | 178 | 2.4% | 0.0% | 0.0% |
| Corner-chain | 3,764 | 3,320 | 6,560 | 15,028 | 296 | 22.8% | 1.6% | 0.0% |
| Corner + lookahead | 9,474 | 7,588 | 16,976 | 37,804 | 611 | 60.4% | 31.2% | 8.0% |
Three things the data suggests
Structure matters more than the next merge. Merge-first averaged 1,973 points, while the corner policy averaged 3,764.
Empty cells are a resource. Policies that preserve space survive longer and have more room to repair a broken number chain.
Lookahead reduces greedy moves. Even one layer of lookahead lifted the average to 9,474 and reached 1024 in 31.2% of games.
How to win 2048: turn the data into a play plan
The benchmark is useful because it points to repeatable decisions, not because an automated policy plays exactly like a person. Use the results as a practical checklist for real 4×4 games.
1. Anchor the largest tile in a corner
A corner reduces the directions from which the largest tile can be disturbed. Build the next-largest values beside it so merges feed inward instead of forcing the anchor through the middle of the board.
2. Treat empty cells as a resource
Do not judge a move only by whether it creates a merge. A move that preserves two or three useful empty cells can be stronger than a greedy merge that fills the board and removes your next options.
3. Keep a descending edge or snake
Organize large values from highest to lower along one edge. The exact pattern can bend, but the principle is consistent: neighbouring large tiles should be close enough that future doubles do not require rebuilding the whole board.
4. Look one move beyond the obvious merge
Before taking a merge, picture where every row or column will land and where a new 2 or 4 could appear. The benchmark’s lookahead policy outperformed the simpler corner policy because it penalized moves that looked good immediately but damaged the next board state.
Common 2048 mistakes that end strong runs
- Moving the anchor tile out of its corner for a small short-term merge.
- Swiping in all four directions without a preferred edge or recovery plan.
- Using every empty cell instead of keeping room for new spawns and correction moves.
- Creating two large tiles far apart, then spending many turns trying to reconnect them.
- Assuming a full-looking board is lost before checking whether adjacent equal tiles can still merge.

Simulation method
The benchmark uses a 4×4 board, two starting tiles, and one new tile after every valid move: 90% chance of 2 and 10% chance of 4. Each policy runs 500 fixed seeds using i × 7919 + 17. These are simple heuristics, not an optimal AI or a model of expert human play.
Use the results to compare decision principles, not as a performance ceiling. Skilled players and deeper search algorithms can score substantially higher.
